Machine-to-machine communications are increasingly exploited in distributed denial of service (DDoS) attacks. The use of IoT devices in synchronized attacks is growing globally, with China listed as the top host country for DDoS weapons, followed at distance by the United States. The most common protocols hackers use to create botnets for DDoS attacks are Network Time Protocol (NTP), Domain Name System (DNS), and Simple Services Discovery Protocol (SSDP). However, new research points to a fast-emerging weapon in botnet arsenals: Constrained Application Protocol (CoAP). CoAP is a service layer protocol used by resource-constrained Internet-connected devices. It’s designed to easily translate to HTTP for simplified integration with the web, but it also meets specialized requirements like multicast support, low overhead and simplicity – all crucial for the proper functioning of Internet of Things (IoT) and Machine-to-Machine (M2M) devices.

A 4 Step Guide to Stronger OT Cybersecurity

Article | April 1, 2020

Security and risk management leaders at organizations around the world are increasingly concerned about cybersecurity threats to their operational technology (OT) networks. A key driver behind this is that cyberthreats, like disruptionware, are increasing in quantity and sophistication all the time. Industrial control system (ICS) networks are categorized as high risk because they are inherently insecure, increasingly so because of expanding integration with the corporate IT network, as well as the rise of remote access for employees and third parties. An example of an IT network within a control system is a PC that’s running HMI or SCADA applications. Because this particular PC wasn’t set up with the initial intention of connecting to IT systems, it typically isn’t managed so can’t access the latest operating system, patches, or antivirus updates. This makes that PC extremely vulnerable to malware attacks. Besides the increased cyberthreat risk, the complexity resulting from IT–OT integration also increases the likelihood of networking and operational issues.

Post-Pandemic Tech Job Market: The Good, Bad and Ugly

Article | April 1, 2020

As we emerge from the worst pandemic in a century, many public- and private-sector employees and employers are reassessing their options within technology and cybersecurity roles. Are boom times coming soon for tech companies, cybersecurity professionals and others? Marketplace.org recently posted the headline, “Are we headed for a Roaring ’20s economy?” Here’s an excerpt: “A year ago, when most of the country was under stay-at-home orders and people were losing jobs at an unprecedented rate, we asked three people who study economic history to explain whether the recession on the horizon was going to look anything like the Great Depression. “With the vaccine rollout well underway, weekly unemployment claims at their lowest level since the pandemic began and consumer confidence rising, we’ve asked them about a different historical comparison: the 1920s.” Meanwhile, NBC News reported “There are now more jobs available than before the pandemic. So why aren't people signing up?” Here’s a quote from that piece: “The number of job vacancies soared to nearly 15 million by mid-March, but discouraged, hesitant and fearful job seekers means many positions are still unfilled, according to new data from online job site ZipRecruiter. “Online job postings plunged from 10 million before the start of the pandemic last year to just below 6 million last May, as lockdowns and shutdown orders forced businesses to close their doors and reduce or lay off workers.” Meanwhile, according to KPMG in the U.K., tech’s job market is growing at the fastest pace in two years. “The move towards new remote and hybrid working arrangements, new spending priorities for businesses around IT infrastructure, automation and the huge shift to online retail are likely to provide a long-term boost to sales and investment in the tech sector,” said KPMG’s chair Bina Mehta. One more — thecyberwire.com just reported that the skills gap is getting wider regarding cybersecurity jobs: “The cybersecurity industry is projected to triple year-over-year through 2022, yet the workforce shortage still stands at millions worldwide. With a 273 percent increase in large-scale data breaches in the first quarter of 2020 alone, employing more cybersecurity professionals is a pressing challenge for both companies looking to hire in-house and cybersecurity agencies alike. “According to the International Information System Security Certification Consortium, there are now more than 4.07 million unfilled cybersecurity positions across the world. Despite high entry salaries, recession-proof job security and plentiful career opportunities, there are simply not enough trained cybersecurity professionals to fill the skills gap.” BAD TREND — AND EVEN SOME UGLY MIXED IN I recently posted a story from the Atlanta Journal-Constitution on LinkedIn entitled “Employers are hiring again but struggling to find workers.” Here’s an excerpt: “Chris New said he has turned down $250,000 in business because he just can’t hire enough laborers and drivers at his Carrollton-based company, Barnes Van Lines. “There are plenty of people without jobs, but unemployment benefits give them too much incentive not to work, he said. ‘We advertise and nobody comes in looking for a job. A lot of people are taking advantage of the system. It’s really killing us.’” Although the focus on this article was not technology or cybersecurity jobs, many of the comments were tech- and cyber-related. Marlin Brandys: So how do they explain people like me with a B.S. in networking and cybersecurity and an NCSP both from 2020 and I can’t even get an interview for a tier 1 help desk job? All these posts and stories from corporate America, universities, government agencies selling the bogus skills gap and shortage story. This platform alone has 1,000s of cyber qualified people able and willing to work in entry level positions at entry level pay and benefits. Stop the madness already. I applied for unemployment 01/08/2021. It’s now 04/19/2021 and I haven’t seen a dime of unemployment compensation. I’ll gladly take an entry-level position in cyber. Quinn Kuzmich: Marlin Brandys - Honestly one of the unspoken truths of the security industry is age discrimination. Sad but true. Dave Howe: Quinn Kuzmich - broadly true across all of IT though. They stand around demanding someone "do something" about the "skills shortage" but exclude 90% of candidates based on an arbitrary checklist, and 75% more based on illegal age, sex or race discrimination, disguised as "culture fit" Joseph Crouse: Marlin Brandys you're overqualified. Marlin Brandys: Joseph Crouse, I wish I could believe that. For some types of positions in the teaching or instructing silo maybe, for entry level information security I do not believe so. Dave Howe: Marlin Brandys - it's difficult to tell. I have seen "entry level" roles demand a CISSP and CEH. Gregory Wilson: 300+ applications and 4 interviews... No job yet... Overqualified, not enough experience, ghosted.... REALITY — I'm over 60 and nobody will hire me... All the BS aside, there are lots of people ready to work... Pay them what they're worth! Dave Howe: I think there is a bigger picture. Welfare shouldn't be so generous as to encourage people to stay on it, but equally, it shouldn't be so stingy as to cause people to struggle to stay afloat (meet rent, put food on the table, however basic, keep the power on) — there is need for balance. Equally though, an entry -evel role where a worker is willing to put in a nominal 40 hours at a routine, boring but not dangerous or unpleasant job should pay sufficient after expenses so as to be able to afford some luxuries above and beyond what welfare provides — if you are no better off, then that job is underpriced and needs either automation to improve output so as to make paying more a better proposition, or automating entirely and the job eliminated. If the job is dangerous, distasteful or involves unsociable hours, then that should be reflected in the pay, above and beyond what a "basic" job should provide. The answer should never be "we need to cut welfare so that they will take my crappy, low paid job out of desperation, because adding automation means upfront costs and I don't want to pay any more" You can join in on that LinkedIn conversation here: SOLUTIONS, PLEASE This Forbes article offers some interesting perspectives on how both employers and employees can succeed in the coming post-COVID cybersecurity world, while offering a new model for our future workforce: “Cybersecurity is a striking example of where the supply-demand gap for personnel is particularly volatile, with companies routinely lacking both the technology and available human capital needed to integrate relevant, highly skilled workers at the same speed as their unprecedented digital transformation. When the COVID-19 pandemic forcibly distributed security teams, organizations were given a new perspective as to how remote teams can de-risk innovation. Now, many are moving to industrialize the 'new normal' of cybersecurity with greater efficiencies across their internal programs and the software development life cycle by seamlessly integrating expert security talent on-demand.” While this coming boom may not be good news for state and local governments who struggle to compete with the private sector for the most talented tech and cyber staff, there are new options opening up for public-sector employees as well. This research finds that many retirees want to come back and work 10 to 20 hours a week, especially if they can work remotely. Many groups are training workers for the post-pandemic job market. I also have spoken with CISOs and other technology leaders in both the public and private sectors who are much more open to hiring out-of-state workers, even though they would never have allowed that before the pandemic. And finally, what about those who can’t find work, despite the supposed “boom times” that are coming? Last year, I wrote this blog describing why some skilled cyber pros are still not getting jobs. Here are just a handful of the reasons I listed there: People are living or looking in the wrong places. They want a local job and do not want to move. (Note: More remote hiring is happening now with COVID-19, but it is still unclear if many of these jobs will go “back to the office” after the pandemic. This leads to hesitancy in taking a job in another part of the country.) Insistence on remote work. While this is easier during the pandemic, some people want 100 percent remote without travel, which can limit options. Also, some hiring managers are not clear if remote jobs will last after the pandemic restrictions are lifted, so they want to hire locally. Company discrimination due to older worker applicants. Yes, I agree with my colleagues that this is alive and well in 2020. Other forms of discrimination exist as well, such as race and gender. Lack of professional networking — especially true during COVID-19. They don’t have personal connections and have a hard time meeting the right people who are hiring or can help them find the right job. Attitude, character, work ethic, humility, etc. I have written several blogs just on this topic, but some people never get the job because they come across in interviews as entitled or too angry or having a bad attitude. They scare off hiring managers. For more on this topic, see “7 reasons security pros fail (and what to do about it)” and “Problem #3 for Security Professionals: Not Enough Humble Pie” and “Problem 5: Are You An Insider Threat?” Putting this all together, I love my brother Steve’s perspective on individual career opportunities and selling your ideas (and yourself) to those both inside and outside your organization: “It’s all about the right product at the right place at the right time at the right price — with the right person delivering the message to the right decision-maker.” FINAL THOUGHTS During a recent vacation to northern Arizona, I found myself working in a coffee shop surrounded by several men and women that were supporting global companies with technology projects. Conversations were all over the map regarding application enhancements and complex deliverables for some industry-leading names. I was frankly a bit shocked that all of this work was being run out of a coffee shop — with a few video conference calls to people’s homes. The “new normal” of global workforces became more of a reality to me, and I see this trend accelerating even after the pandemic.

5 Digital Transformation-Driven Cybersecurity Considerations

Article | April 1, 2020

On their road to recovery from the pandemic, businesses face unique dilemmas. This includes substantial and entirely necessary investments in digital transformation, however tight budgets are making such endeavors difficult if not impossible. Businesses continue to struggle with pivots like adopting new digital platforms, shifting their corporate model to resolve supply chain disruption and enabling a remote workforce. The inability for businesses to quickly adopt technologies that support digital transformation processes, including identity-based segmentation, virtual desktop interfaces and full-stack cloud, is hindering their ability to adequately address new threats and even to test new security systems and protocols. “Now more than ever, it’s imperative to remediate risk exposure and vulnerabilities within an organization’s existing systems—optimally from the get-go,” urges cybersecurity expert Nishant Srivastava, Cyber Security Architect and field expert at Cognizant—an IT Solutions and Services firm for which he's focused on designing and implementing Identity and Access Management (IAM) solutions. “Biggest threats should get highest priority, of course, but the magnitude or even likelihood of a threat should not be the sole consideration. Organizations should also look at other forms of value that new technologies can bring.” Below Srivastava, a senior-level IAM, governance and cyber risk authority, offers key digital security vulnerabilities businesses need to be mindful of given increased digital dependency amid the pandemic. Heed these best practices to help keep your company—and customers—uncompromised. Consumer-Facing App Gaps For consumer-facing web applications, some of the biggest security threats include path traversal, cross-site scripting (XSS), SQL injections and remote command execution. Of course, protecting customer data is an utmost security concern and breaches abound. One of the biggest challenges to address these kind of issues lies with lacking human resources. There is a lack of aptly trained and skilled security staff in even the most sophisticated of regions, which is cultivating a gap in cybersecurity skills across the globe. It goes without saying that employee training and investing in highly-qualified staff are among the best ways to establish, maintain and uphold security levels of consumer facing apps. Rifts, however small, can induce excessive damage and losses. eCommerce Exposure Online delivery businesses that are aware of security risks would be wise to introduce more secure logins, automatic logouts and random shopper ID verification and are preventing shoppers from swapping devices when ordering. Such measures will help thwart breaches that expose of customer names, credit card information, passwords, email addresses and other personal and sensitive information. Companies selling goods or services online also should not launch without a secure socket layer (SSL) connection. It will encrypt all data transfer between the company’s back end server and the user's browser. This way, a hacker won’t be able to steal and decode data even if he or she manages to intercept web traffic. Another useful strategy is to enforce password limitations. Passwords should be as complicated as possible with a combination of symbols, numbers and letters. Investing in a tokenization system is worthwhile because any hacker who accesses the back end system can read and steal sensitive information, which is held in the database as plain text. Some payment providers tokenize cardholder information, which means a token replaces the raw data so the database then holds a token rather than the real data. If someone steals it, they can’t do anything with it because it’s just a token. Ransomware Recourse Ransomware threats are escalating, which is why those doing business digitally should enforce a multi-layer security strategy that incorporates data loss prevention software, file encryption, personal firewall and anti-malware. This will protect both a company’s infrastructure and its endpoint. Data backups are key because there’s still a mild chance of a breach even with all of the aforementioned security solutions in place. The easiest and most effective way to minimize cyberattack damage is to copy files to a separate device. This very reliable form of backup makes it possible for people to recommence work as usual with little to no downtime, and all their computer files intact, should an attack occur. Gone Phishing Gmail blocks over 100 million COVID-related phishing emails every day, but more than 240 million are sent. That means less than half sent via Gmail alone are blocked. Experts cite imposing limits on remote desktop protocol (RDP) access, multifactor authentication for VPN access, in-depth remote network connection analysis and IP address whitelisting as some of the best strategies to maintain security. In addition, businesses should secure externally facing apps like supplier portals that use risk-based and multifactor authentication—particularly for apps that would let a cybercriminal divert payments or alter user bank account details. Shielding Teleconferences The shift to remote work after the pandemic hit has given cybercriminals more and more opportunities, directing their focus on the tools people use for work. It’s important that people recognize their vulnerabilities, particularly while they work from home. Among these are hacked videoconference passwords and unprotected videoconference links, which criminals can use to access an organization’s network without authorization. Many people who work from home do not use secured networks, unknowingly and unintentionally. Many are just not aware of the risks. To avoid online teleconference security issues, meetings should always be encrypted. This means a message can only be read by the recipient intended and that the host must be present before the meeting begins. There should also be waiting rooms for participants. Screen share watermarks, locking a meeting, and use of audio signatures are additional recommendations. When asked what his best advice would be to tweak security for a workforce that’s predominately working remotely, Nishant says that companies should start by analyzing the basics (like those specified above) against the backdrop of a wide range of ever-escalating and evolving threats. “Employees should use dual-factor authentication and make sure apps, mobile phones and laptops are updated and that available patches and updates are always installed,” he says. “They should certainly be wary of all information requests and verify the source. These even include unexpected calls or emails seemingly from colleagues.” Srivastava also pointed out that insiders at the CIO Symposium in July 2020 agreed that the pandemic packed years of digital transformation into just a few weeks. The use of third parties emerged as a major security concern to take into account. For instance, some employees abroad were unable to move their computers to their homes, so employers rushed to supply them with new equipment. In the process, some of it was not set up correctly thus compromising security. Companies should have done more to determine out whether individuals were using technology properly, such as if employees were sharing work devices or using their own personal equipment. On the plus side, the shift toward working from home sped up multi-factor authentication adoption. This is a great opportunity that today’s digitally-driven businesses should take advantage of. In short, Srivastava advocates taking a zero-trust approach. “It might sound harsh, but this is the idea that you can’t trust devices, people and apps by default,” he says. “Everything needs to be authorized and authenticated. Users should always verify and never trust, and businesses should act as if there has already been a breach and work to shore up weak links in the security chain. Finally, businesses should give access to information and data to as few people as possible—and wholly ensure those who do have access are appropriately trained to recognize when a red flag presents. By employing all or even some of the advice above, businesses can continue to thrive as the digital transformation age unfolds—and do so more confidently and contently all around.
