Success in a DevSecOps enterprise hinges on delivering worth to the tip consumer, not merely finishing intermediate steps alongside the best way. Organizations and packages usually wrestle to attain this attributable to a wide range of elements, reminiscent of an absence of clear possession and accountability for the aptitude to ship software program, practical siloes versus built-in groups and processes, lack of efficient instruments for groups to make use of, and an absence of efficient sources for group members to leverage to rapidly rise up to hurry and enhance productiveness.

An absence of a central driving drive may end up in siloed items inside a given group or program, fragmented resolution making, and an absence of outlined key efficiency metrics. Consequently, organizations could also be hindered of their capability to ship functionality on the velocity of relevance. A siloed DevSecOps infrastructure, the place disjointed environments are intertwined to type an entire pipeline, causes builders to expend vital effort to construct an utility with out the help of documentation and steerage for working throughout the supplied platforms. Groups can’t create repeatable options within the absence of an end-to-end built-in utility supply pipeline. With out one, effectivity suffers, and pointless practices lavatory down all the course of.

Step one in reaching the worth DevSecOps can carry is to grasp how we outline it:

a socio-technical system made up of a group of each software program instruments and processes. It isn’t a computer-based system to be constructed or acquired; it’s a mindset that depends on outlined processes for the fast growth, fielding, and operations of software program and software-based methods using automation the place possible to attain the specified throughput of creating, fielding, and sustaining new product options and capabilities.

DevSecOps is thus a mindset that builds on automation the place possible.

The target of an efficient DevSecOps evaluation is to grasp the software program growth course of and make suggestions for enhancements that may positively influence the worth, high quality, and velocity of supply of merchandise to the tip consumer in an operationally steady and safe method. A complete evaluation of present capabilities should embrace each quantitative and qualitative approaches to gathering information and figuring out exactly the place challenges reside within the product supply course of. The scope of an evaluation should think about all processes which can be required to subject and function a software program product as a part of the worth supply processes. The aperture by which a DevSecOps evaluation group focuses its work is wider than the instruments and processes sometimes regarded as the software program growth pipeline. The evaluation should embody the broader context of all the product supply pipeline, together with planning levels, the place functionality (or worth) wants are outlined and translated into necessities, in addition to post-deployment operational phases. This wider view permits an evaluation group to find out how nicely organizations ship worth.

There are a myriad of overlapping influences that may trigger dysfunction inside a DevSecOps enterprise. Trying from the surface it may be troublesome to peel again the layers and successfully discover the foremost causes. This weblog focuses on the right way to conduct a DevSecOps evaluation with an method that makes use of 4 methodologies to investigate an enterprise from the angle of the practitioner utilizing the instruments and processes to construct and ship precious software program. Taking the angle of the practitioner permits the evaluation group to floor probably the most instantly related challenges going through the enterprise.

A 4-Pronged Evaluation Methodology

To border the expertise of a practitioner, a complete evaluation requires a layered method. This sort of method will help assessors collect sufficient information to grasp each the total scope and the precise particulars of the builders’ experiences, each optimistic and damaging. We take a four-pronged method:

Immersion: The evaluation group immerses itself into the event course of by both creating a small, consultant utility from scratch, becoming a member of an current growth group, or different technique of gaining firsthand expertise and perception within the course of. Avoiding particular therapy is vital to assemble real-world information, so the evaluation group ought to use means to grow to be a “secret shopper” wherever attainable. This additionally permits the evaluation group to determine what the true, not simply documented, course of is to ship worth.
Statement: The evaluation group instantly observes current utility growth groups as they work to construct, check, ship, and deploy their functions to the tip customers. Observations ought to cowl as a lot of the value-delivery course of as practicable, reminiscent of consumer engagement, product design, dash planning, demos, retrospectives, and software program releases.
Engagement: The evaluation group conducts interviews and targeted dialogue with growth groups and different related stakeholders to make clear and collect context for his or her expertise and observations. Ask the practitioners to point out the evaluation group how they work.
Benchmarking: The evaluation group captures out there metrics from the enterprise and its processes and compares them with anticipated outcomes for related organizations.

To attain this, an evaluation group can use ethnographic analysis strategies as described within the Luma Institute Innovating for Individuals System. Interviewing, fly-on-the-wall remark, and contextual inquiry enable the evaluation group to look at product groups working, conduct follow-up interviews about what they noticed, and ask questions on habits and expectations that they didn’t observe. By utilizing the walk-a-mile immersion method, the evaluation group can communicate firsthand to their experiences utilizing the group’s present instruments and processes.

These strategies assist be sure that the evaluation group understands the method by getting firsthand expertise and doesn’t overly depend on documentation or the biases of remark or engagement topics. Additionally they allow the group to higher perceive what they’re observing or listening to about from different practitioners and establish the facets of the worth supply course of the place enhancements are extra possible available.

The two Dimensions of Assessing DevSecOps Capabilities

To precisely assess DevSecOps processes, one wants each quantitative information (e.g., metrics) to pinpoint and prioritize challenges primarily based on influence and qualitative information (e.g., expertise and suggestions) to grasp the context and develop focused options. Whereas the evaluation methodology mentioned above supplies a repeatable method for gathering the mandatory quantitative and qualitative information, it isn’t adequate as a result of it doesn’t inform the assessor what information is required, what inquiries to ask, what DevSecOps capabilities are anticipated, and so on. To deal with these questions whereas assessing a corporation’s DevSecOps capabilities, the next dimensions needs to be thought-about:

a quantitative evaluation of a corporation’s efficiency in opposition to educational and trade benchmarks of efficiency
a qualitative evaluation of a corporation’s adherence to established greatest practices of high-performing DevSecOps organizations

Inside every dimension, the evaluation group should take a look at a number of essential facets of the worth supply course of:

Worth Definition: How are consumer wants captured and translated into merchandise and options?
Developer Expertise: Are the instruments and processes that builders are anticipated to make use of intuitive, and do they cut back toil?
Platform Engineering: Are the instruments and processes nicely built-in, and are the suitable facets automated?
Software program Growth Efficiency: How efficient and environment friendly are the event processes at constructing and delivering practical software program?

Since 2013, Google has revealed an annual DevSecOps Analysis and Evaluation (DORA) Speed up State of DevOps Report. These reviews assemble information from hundreds of practitioners worldwide and compile them right into a complete report breaking down four-to-five key metrics to find out the general state of DevSecOps practices throughout all kinds of enterprise sorts and sectors. An evaluation group can use these reviews to rapidly key in on the metrics and thresholds that analysis has proven to be vital indicators of total efficiency. Along with the DORA metrics, the evaluation group can conduct a literature seek for different publications that present metrics associated to a selected software program architectural sample, reminiscent of real-time resource-constrained cyber-physical methods.

To have the ability to evaluate a corporation or program to trade benchmarks, such because the DORA metrics or case research, the evaluation group should have the ability to collect organizationally consultant information that may be equated to the metrics discovered within the given benchmark or case research. This may be achieved in a mix of the way, together with gathering information manually because the evaluation group shadows the group’s builders or stitching collectively information collected from automated instruments and interviews. As soon as the info is collected, visualizations such because the determine under might be created to point out the place the given group or program compares to the benchmark.

From a qualitative perspective, the evaluation group can use the SEI’s DevSecOps Platform Unbiased Mannequin (PIM), which incorporates greater than 200 necessities one would count on to see in a high-performing DevSecOps group. The PIM permits packages to map their present or proposed capabilities onto the set of capabilities and necessities of the PIM to make sure that the DevSecOps ecosystem into account or evaluation implements the most effective practices. For assessments, the PIM supplies the aptitude for packages to seek out potential gaps by wanting throughout their present ecosystem and processes and mapping them to necessities that specific the extent of high quality of outcomes anticipated. The determine under exhibits an instance abstract output of the qualitative evaluation by way of the ten DevSecOps capabilities outlined throughout the PIM and total maturity degree of the group beneath evaluate. Confer with the DevSecOps Maturity Mannequin for extra data relating to the usage of the PIM for qualitative evaluation.

Charting Your Course to DevSecOps Success

By using a multi-faceted evaluation methodology that mixes immersion, remark, engagement, and benchmarking, organizations can acquire a holistic view of their DevSecOps functionality. Leveraging benchmarks just like the DORA metrics and reference architectures just like the DevSecOps PIM supplies a structured method to measuring efficiency in opposition to trade requirements and figuring out particular areas for enchancment.

Purposefully taking the angle of the practitioners tasked with utilizing the instruments and processes to ship worth helps the assessor focus their suggestions for enhancements on the areas which can be prone to have the best influence on the supply of worth in addition to establish these facets of the method that detract from the supply of worth.

Keep in mind, the journey in the direction of a high-performing DevSecOps atmosphere is iterative, ongoing, and targeted on delivering worth to the tip consumer. By making use of data-driven quantitative and qualitative strategies in performing a two-dimensional DevSecOps evaluation, an evaluation group is nicely positioned to establish unbiased observations and make actionable strategic and tactical suggestions. Common assessments are very important to trace progress, adapt to evolving wants, and make sure you’re constantly delivering worth to your finish customers with velocity, safety, and effectivity.

I am engaged on an iOS recording app utilizing AVAudioEngine and AVAudioSession. The aim is to report in stereo at 48kHz utilizing the built-in iPhone microphone (on fashions that help stereo recording, like iPhone XS and up).

I’ve carried out full management over the audio session and mic configuration, together with choosing information sources and setting enter orientation, polar patterns, and pattern charges.

Right here’s the related code when establishing stereo recording:

if configuration.isStereo {
    attempt session.setPreferredSampleRate(16_000) // <- that is the one setting that constantly works
    attempt session.setPreferredInputNumberOfChannels(2)
    attempt session.setPreferredInputOrientation(.portrait)
    // choose the proper information supply and polar sample earlier than this
} else {
    attempt session.setPreferredSampleRate(48_000)
    attempt session.setPreferredInputNumberOfChannels(1)
}

Downside:

It doesn’t matter what I do, stereo enter all the time finally ends up utilizing 16kHz pattern charge. Even when I explicitly request 48_000 earlier than establishing the audio engine, it silently drops to 16_000.

Mono recordings work high quality at 48kHz.

Stereo recordings are all the time downsampled to 16kHz.

The enter format printed from inputNode.inputFormat(forBus: 0) confirms this.

I’ve verified the chosen enter information supply is “Framsida” (entrance mic), stereo is on the market, and polar sample is stereo. I am utilizing a safeSwitchInputConfiguration() helper that absolutely deactivates the session earlier than reconfiguring to keep away from race situations.

Right here’s a snippet from the logs:

Began recording with 2 ch @ 16000.0 Hz
Enter iPhone Mikrofon data-source: Non-obligatory("Framsida"), stereo-available: true

What I’ve Tried:

setPreferredSampleRate(48_000) earlier than/after activating the session.

Switching between .playAndRecord and .report session classes.

Attempting totally different enter orientations and polar patterns.

Deactivating/activating the session earlier than configuration adjustments.

Verified with a number of gadgets that help stereo enter.

Questions:

Is stereo at 48kHz really supported on iOS (particularly with the built-in mic)?

Has anybody managed to get 2ch @ 48000Hz from AVAudioEngine with AVAudioInputNode?

Might this be a {hardware} limitation or an undocumented OS constraint?

Is CoreAudio or AudioUnit a extra viable route for this?

Bonus Information:

I do see stereo-available: true, and I can change between “Framsida” and “Undertill” as enter information sources, and polar patterns like omnidirectional, subcardioid, and stereo can be found relying on the chosen supply.

Regardless of all that, the system nonetheless provides me 16kHz.

Any insights from anybody who’s cracked this is able to be vastly appreciated.

New COVID variant ‘Stratus’ is spreading within the U.S. and worldwide – NanoApps Medical – Official web site

A brand new COVID variant is climbing the ranks within the U.S., changing into the third-most widespread pressure of the summer season.

Variant XFG, colloquially generally known as “Stratus,” was first detected in Southeast Asia in January however accounted for lower than about 0% of instances in the US till Might. By late June, it was estimated to account for as much as 14%, in keeping with the Facilities for Illness Management and Prevention (CDC).

The World Well being Group (WHO) added XFG to its watchlist however evaluated the extra public well being threat posed by the variant as “low” on the world stage in a late June report, during which it additionally suggested that at present accredited COVID-19 vaccines are “anticipated to stay efficient to this variant towards symptomatic and extreme illness.”

Right here’s what we find out about XFG.

What’s COVID variant XFG?

XFG is a mix of COVID-19 variants F.7 and LP.8.1.2, the latter of which is at present the second most outstanding pressure within the U.S.

The variant’s mutations might improve XFG’s means to evade immune responses, however its binding conduct reveals that it’s much less more likely to be extremely contagious than different dominant variants, Subhash Verma, microbiology and immunology professor on the College of Nevada, Reno, instructed USA TODAY.

“There may be at present no clear proof that XFG causes extra extreme illness or considerably completely different signs than earlier Omicron variants,” mentioned Verma. “Importantly, there are not any instant public well being issues related to this variant.”

How widespread is XFG?

Whereas XFG has been rising and spreading worldwide, it has but to change into the predominant supply of an infection in the US.

The CDC has moved to utilizing longer timeframes for COVID monitoring resulting from low reporting from states. In keeping with the newest knowledge for the two-week interval ending June 21, XFG accounted for 14% of U.S. instances, making it the third most-prevalent pressure after NB.1.8.1 (43%) and LP.8.1 (31%).

The prominence of XFG in the US considerably elevated within the weeks main as much as the final report, accounting for 0% of instances by means of March earlier than reaching 2% in April, 6% in late Might, 11% in early June and 14% in late June.

WHO tracked an uptick in XFG worldwide in June as effectively, with the June report together with knowledge from 38 nations exhibiting that XFG accounted for less than 7.4% of optimistic exams within the first week of Might however 22.7% by the final.

USA TODAY has reached out to the CDC for extra details about the unfold of COVID variants in July and August.

What are the signs of XFG?

There is no such thing as a proof that XFG causes any distinct signs from different variants, mentioned Verma. Nevertheless, hoarseness has been anecdotally related to the pressure, in keeping with social media posts and information experiences.

The CDC outlines the next as widespread COVID-19 signs:

Fever or chills
Cough
Shortness of breath or issue respiratory
Sore throat
Congestion or a runny nostril
New lack of style or scent
Fatigue
Muscle or physique aches
Headache
Nausea or vomiting

The CDC advises looking for medical care in the event you expertise any of the next signs:

Software program is a rising element of right now’s mission-critical techniques. As organizations turn out to be extra depending on software-driven expertise, safety and resilience dangers to their missions additionally enhance. Managing these dangers is simply too typically deferred till after deployment on account of competing priorities, reminiscent of satisfying value and schedule targets. Nonetheless, failure to deal with these dangers early within the techniques lifecycle can’t solely enhance operational impression and mitigation prices, however it might additionally severely restrict administration choices.

For Division of Protection (DoD) weapon techniques, it’s particularly necessary to handle software program safety and resilience dangers. Proactively figuring out and correcting software program vulnerabilities and weaknesses minimizes the danger of cyber-attacks, weapons system failures, and different disruptions that might jeopardize DoD missions. The GAO has recognized software program and cybersecurity as persistent challenges throughout the portfolio of DoD weapon techniques. To deal with these challenges, acquisition packages ought to begin managing a system’s safety and resilience dangers early within the lifecycle and proceed all through the system’s lifespan.

This submit introduces the Safety Engineering Framework, an in depth schema of software-focused engineering practices that acquisition packages can use to handle safety and resilience dangers throughout the lifecycle of software-reliant techniques.

Software program Assurance

Software program assurance is a stage of confidence that, all through its lifecycle, software program capabilities as meant and is freed from vulnerabilities, both deliberately or unintentionally designed or inserted as a part of the software program. Software program assurance is more and more necessary to organizations throughout all sectors due to software program’s rising affect in mission-critical techniques. Managing software program assurance is a problem due to the expansion in functionality, complexity, and interconnection amongst software-reliant techniques.

For instance, think about how the scale of flight software program has elevated over time. Between 1960 and 2000, the extent of general system performance that software program supplies to navy plane pilots elevated from 8 % to 80 %. On the identical time, the scale of software program in navy plane grew from 1,000 strains of code within the F-4A to 1.7 million strains of code (MLOC) within the F-22 and 8 million strains within the F-35. This development is predicted to proceed over time. As software program exerts extra management over complicated techniques (e.g., navy plane), the potential danger posed by vulnerabilities will enhance correspondingly.

Software program Defects and Vulnerabilities: A Lifecyle Perspective

Determine 1 beneath highlights the speed of defect introduction and identification throughout the lifecycle. This was derived from knowledge introduced within the SEI report Reliability Validation and Enchancment Framework. Research of safety-critical techniques, notably DoD avionics software program techniques, present that 70 % of all errors are launched throughout necessities and structure design actions. Nonetheless, solely 20 % of the errors are discovered by the top of code growth and unit check, whereas 80.5 % of the errors are found at or after integration testing. The rework effort to appropriate necessities and design issues in later phases will be as excessive as 300 to 1,000 instances the trouble of in-phase correction. Even after the rework, undiscovered errors are prone to stay.

Determine 1: Fee of Defect Introduction and Identification throughout the Lifecycle

Given the complexities concerned in creating large-scale, software-reliant techniques, it’s comprehensible that no software program is freed from dangers. Defects exist even within the highest high quality software program. For instance, best-in-class code can have as much as 600 defects per MLOC, whereas average-quality code usually has round 6,000 defects per MLOC, and a few of these defects are weaknesses that may result in vulnerabilities. Analysis signifies that roughly 5 % of software program defects are safety vulnerabilities. Because of this, best-in-class code can have as much as 30 vulnerabilities per MLOC. For average-quality code, the variety of safety vulnerabilities will be as excessive as 300 per MLOC. You will need to notice that the defect charges cited listed here are estimates that present basic perception into the problem of code high quality and variety of vulnerabilities in code. Defect charges in particular initiatives can range enormously. Nonetheless, these estimates spotlight the significance of decreasing safety vulnerabilities in code throughout software program growth. Safe coding practices, code evaluations, and code evaluation instruments are necessary methods to determine and proper recognized weaknesses and vulnerabilities in code.

As illustrated in Determine 1, safety and resilience should be managed throughout the lifecycle, beginning with the event of high-level system necessities by means of operations and sustainment (O&S). Program and system stakeholders ought to apply main practices for buying, engineering, and deploying safe and resilient software-reliant techniques. In 2014, the SEI initiated an effort to doc main practices for managing safety and resilience dangers throughout the techniques lifecycle, offering an strategy for constructing safety and resilience right into a system slightly than bolting them on after deployment. This effort produced a number of cybersecurity engineering options, most notably the Safety Engineering Threat Evaluation (SERA) methodology and the Acquisition Safety Framework (ASF). Late final yr, the SEI launched the Safety Engineering Framework.

Safety Engineering Framework (SEF)

The SEF is a set of software-focused engineering practices for managing safety and resilience dangers throughout the techniques lifecycle, beginning with necessities definition and persevering with by means of O&S. It supplies a roadmap for constructing safety and resilience into software-reliant techniques previous to deployment and sustaining these capabilities throughout O&S. The SEF builds on the foundational analysis of SERA and the ASF, offering in-depth steering that elaborates on main engineering practices and methods to carry out them.

SEF practices assist be sure that engineering processes, software program, and instruments are safe and resilient, thereby decreasing the danger that attackers will disrupt program and system data and belongings. Acquisition packages can use the SEF to evaluate their present engineering practices and chart a course for enchancment, in the end decreasing safety and resilience dangers in deployed software-reliant techniques.

Safety and Resilience

At its core, the SEF is a risk-based framework that addresses each safety and resilience:

Threat administration supplies the inspiration for managing safety and resilience. In actual fact, danger administration strategies, instruments, and strategies are used to handle each. Nonetheless, safety and resilience view danger from totally different views: Safety considers dangers from a safety viewpoint, whereas resilience considers danger from a perspective of adapting to situations, stresses, assaults, and compromises. As proven in Determine 2, there’s some overlap between the danger views of safety and resilience. On the identical time, safety and resilience every have distinctive dangers and mitigations.

Determine 2: Threat Views: Safety Versus Resilience

The SEF specifies practices for managing safety and resilience dangers. The attitude the group adopts—safety, resilience, or a mix of the 2—influences the dangers an acquisition group considers throughout an evaluation and the set of controls which can be accessible for danger mitigation. Due to the associated nature of safety and resilience, the SEF (and the rest of this weblog submit) makes use of the time period safety/resilience all through.

SEF Construction

As illustrated in Determine 3, the SEF has a hierarchy of domains, objectives, and practices:

Domains occupy the highest stage of the SEF hierarchy. A website captures a singular administration or technical perspective of managing safety/resilience dangers throughout the techniques lifecycle. Every area is supported by two or extra objectives, which type the following stage of the SEF hierarchy.
Targets outline the capabilities {that a} program leverages to construct safety/resilience right into a software-reliant system. Associated objectives belong to the identical SEF area.
Practices inhabit the ultimate and most detailed stage within the hierarchy. Practices describe actions that assist the achievement of SEF objectives. The SEF phrases practices as questions. Associated practices belong to the identical SEF purpose.

Determine 3: SEF Group and Construction

The SEF contains 3 domains, 13 objectives, and 119 practices. The following part describes the SEF’s domains and objectives.
