CYBR650 Week 12 Final Entry

I made it through all the week to week 12! This class has been exciting, informative, and very stimulating. Believe it or not, the most difficult part of this course was developing my own threat model. The feedback from the professor and my classmates helped tremendously to help me stay on track! One of the best parts of this class was the ability to review other classmates’ assignments. This gave me a great opportunity to learn from others in the class. I believe this class will help to push me into the cyber security world in the company I work for, and I know the objectives and concepts taught in this class will be a great starting point for me. I know that I can now analyze the various elements of an information system, conduct an analysis for risks, threats, and vulnerabilities, and develop a process model to help identify the existing and future threat landscape.

This blog assignment was one of my favorites, as it gave me an opportunity to explore other topics related to current trends in cyber security, and to post my thoughts and opinions. I now browse through several online sites weekly in search of the latest news related to the world of cyber security, and this is a habit I will continue long after the class is over. One of my preferred online sources is Security Week. This online magazine was ablaze this week as the European Union’s new data protection rules went into effect. The EU’s General Data Protection Regulation (GDPR) seem to have far-reaching effects, as I have been receiving a large amount of emails and mail with privacy update notices. This new law is supposed to provide greater protection of people's online information, but as with many other consumers, I am skeptical. I appreciate that individuals must explicitly grant permission for their data to be used, but believe big companies will soon find loopholes or other ways around it.

Now that we have the EU’s GDPR in effect, how about someone start working on protecting us from the real bad guys? I mean, it’s great that the GDPR is focused on big companies like Facebook, WhatsApp, and Twitter, but is going after the hackers and other illegal actors on the cyber security stage? The news is currently highlighting the attack by alleged Russian hackers who have infected at least 500,000 routers and storage devices in over 50 countries. Now the FBI is warning that the attackers could collect user information or shut down network traffic on these home and office routers. Read more here https://www.reuters.com/article/us-usa-cyber-routers/fbi-warns-russians-hacked-hundreds-of-thousands-of-routers-idUSKCN1IQ2DY and here https://www.securityweek.com/us-disrupts-russian-botnet-500000-hacked-routers. Now that we’ve potentially ordered big corporations to place better security measures to comply with the GDPR, we need to also invest even more time and resources into going after the bad guys, and stopping them before they can attack.

My final entry for this class is a synopsis of a really good article on Security Week by Joshua Goldfarb. He talks about the 10 security behaviors that anger us. It is one of the most-commonsense pieces of security advice I’ve read in a long time. One of the 10 security behaviors is fire fighting; where a security team seems to running from one emergency to another. Companies often bring this upon themselves, when they refuse to threat model, or to hire enough properly trained It professionals. The result is a reactive one, where the security team has to put out endless ‘security’ fires. Another security behavior is probably the most common one: writing down passwords. We all know that writing down passwords is considered a terrible security habit. Yet, our password policies dictate that we create complex passwords that include upper and lower case letters, mixed with numeric and special characters, and with a particular length. If we didn’t write down our passwords somewhere, we’d be kicked out of our computer systems constantly. Companies need to help us with password management systems so we can keep track of all these unique passwords we need.

The Action Plan CYBR650 Week 10

Week 10 feels good as we near the finishing line of this class. The assignments are really empowering, as they have been helping me to understand a part of our company business that I’m not usually involved in. Developing the action plan really helped me to get a better appreciation of our IT team. The action plan is a crucial document that could go a long way in mitigating the risks that have been identified. I believe one of the challenges our IT folks face is (sometimes) their inability to communicate their findings in the kind of verbiage that upper management (who are often not technical) understands. This is such a vital piece of the equation; if the action plan properly conveys to management how you conducted your assessment, along with your results and the plan to address the threats, vulnerabilities, and risks, chances are management would approve it. The learning objectives for these two weeks (9 and 10) gave us the opportunity to review and provide constructive criticism on the action plan provide by our classmates, and I really enjoyed it. While giving feedback, I am also taking away ideas on how I can improve my own document.

A good action plan is extremely important for improved security in any organization. Just identifying threats and vulnerabilities is not good enough. Action must be taken to mitigate these risks, and that’s where the action plan with good security recommendations come it handy. Many security breaches can be avoided if organizations simply implemented some common security controls and best practices, like updating configurations and keeping operating systems up to date with latest security patches. Even the best of hardware and software tools, if not properly configured, cannot resist cyber attackers. Hackers seem to be at the top of their game, employing more enhanced and sophisticated techniques to perform their exploits. Successful data breaches yield a big payload to attackers, and often have a major impact on organizations, including loss of revenue, loss of customers, damage to their brand, and even fines!

Many companies without a dedicated security team are now getting into the habit of using a managed security provider, much like in the case of Harry and Mae’s Inc. It can often be more cost effective and with less distractions to an internal staff. The idea is to go on the offensive, rather then being defensive. While we embrace rapidly advancing technologies, we have to understand these technologies often pose a serious security risk to organizations. IT staff have to stay current on new threats and security best practices. In today’s world of compliance with industry standards and federal and state regulations, companies have to be very serious about security; non-compliance can often result in hefty fines and other consequences. The action plan is useful in that it prioritizes the vulnerabilities, giving companies the chance to work on those that pose a major threat to the organization.

One very popular strategy in many action plan recommendations for better security is the development and implementation of a strong security policy, along with ongoing employee education and training, and monitoring for compliance. Employee education and training is beneficial to the employee and ultimately to the company. As employees practice good security measures, especially when it comes to passwords, etc., they’re doing their part to help keep the company safe and secure from data breaches. Employee education and training also helps to improve productivity, and it definitely goes a long way in adherence to quality and other industry standards. The action plan also provides a man to help track action ownership, resource estimates, priorities, target dates, etc. As it defines the recommended risk and compliance-related mitigation actions needed to improve the organization’s risk posture, it also provides a way to identify the company’s high priority assets and the owners or prime points of contact for these assets, which could come in very useful during or after an attack.

Threats and Vulnerabilities CYBR650 Week 9

Delving into week 9 brings the stark reminder that no one: no company, no organization, be it private or government, profitable or non-profit, no one is exempt from a cyber attack, no one is ever 100% secure from a cyber attack. While we laud the rapid pace of technological advances, and the comfort it brings us (I’m writing this blog while working from home today, so I don’t want to be too hypocritical), the problem is that this same technology is misused tremendously by cyber attackers. Despite the increasing wave of data breaches over the past few years to companies like Home Deport, Chase Bank, and Experian, it seems like companies are not doing their best to keep their data (and our data) as safe as possible. Just a few days ago Twitter announced that a bug in their system may have exposed user passwords internally. While the company quickly said that no breach occurred, and must be commended for coming out publicly very quickly, the fact remains that this information was available to hackers for a period of time, so Twitter can never be 100% sure that the compromised data was not acquired by attackers! I am leery that Twitter’s own internal investigation showed no signs of a breach or misuse; let’s get an independent auditor to confirm Twitter’s findings! Read more about it here: https://www.trendmicro.com/vinfo/us/security/news/online-privacy/change-your-passwords-twitter-bug-exposes-user-passwords.

The Twitter accounts’ compromise and the other data breaches is a reminder to all users, personal or corporate, of the need to practice good security measures on social media accounts. The top on the security list is creating and using strong passwords that follow complexity rules. If your password is easy for you to guess or remember, it is more likely to be an easy target for hackers. Also, always check your security and privacy settings. Don’t use the system default settings. Adjust the default settings as much as necessary so you can protect your personal information.

Every time I hear about a new technology or device being introduced, I get a little fearful. Take Amazon’s virtual assistant, Alexa, for example. Amazon has made several Alexa-enabled devices, and other manufacturers are building Alexa into many types of devices like phones and thermostats. I thought to myself: great; now let’s say see what hackers will do with it! Just two weeks ago, an article on the Trend Micro website stated that Alexa can be programmed to eavesdrop on its users and transcribe the information, which is a great potential for hackers to steal private information. As far as most (if not all) users understand it, the Alexa digital assistant is supposed to end the active session until prompted for another active session. However, it seems attackers can prompt Alexa to believe it has informed the user that the device is still actively listening, and can transcribe and send the information to the programmers. Read more about it at https://www.trendmicro.com/vinfo/us/security/news/vulnerabilities-and-exploits/alexa-can-listen-indefinitely-potentially-exploited-to-transcribe-information-to-cybercriminals.

           The need for education of users in the area of cyber security and general security measures remains strong. People must understand that they are responsible for maintaining the security on their products, and should not rely entirely on vendors and manufacturers. While manufacturers may identify vulnerabilities and provide patches and system updates, it is still the user’s responsibility to actually download these firmware and software updates. Good security practices, like using strong passwords, not using the same passwords on different accounts, and changing passwords regularly should be followed. Operating systems and browsers should always be kept up-to-date in regards to patches and security updates. And make sure to keep regular backups of data; this comes in useful if an attacker targets and corrupts your data – a backup can save you time, money, and a lot of headaches.
