Definition of Cyber Security as a Discipline: It is a discipline that deals with the security of electronic gadgets connected through the internet like networks, computers, mobile devices, and software within those systems from any kind of malicious software. It is also considered Electronic Information Security. The professional of this discipline is protecting all the gadgets safely connected to the internet. Cyber Security Experts are supposed to look for any weakness in the system, software, or electronic device from outside. They protect the overall system from intrusion through the internet. You learn various methods, techniques or develop strategies based on the solid knowledge ground to protect the system. The professional from this discipline also provides inputs in the development of software, to make the software protected from possible threats. Expert is constantly monitoring the overall system for any possible intruders attack. The development of new protocols and security systems based on the threat intensity and level is also the task of professionals. The main topics of this discipline may be mobile device protection from online viruses, warms, or hacking threats, developing and maintaining the privacy of the individual users, counteracting against any data breach, ensuring safe computing, online scams, etc. Brief History of the Discipline: An Army General SUN Tzu Wu in China, about 20 years ago has written in his book “The Art of War” about vulnerabilities. His book is about series of engagements with the enemy. He says, “One who knows the enemy and knows himself will not be in danger in 100 battles, One who does not know the enemy but knows himself, will sometimes win...
Figures show one in ten employees will have their security username or password compromised by cyber criminals. For people operating access and security systems, preventing this kind of cyber breach is even more important. Tim Northwood, director of Inner Range, discusses how Two Factor Authentication (2FA) provides an extra layer of cyber security for customers. Benefits of 2FA Two Factor Authentication (2FA), which is offered by Inner Range’s intelligent integrated access and security management system, Integriti, ensures operators must present their usual username and password as well as an additional security credential. This includes extra security passwords or memorable information, biometrics such as thumb or finger prints and facial scans, or a code received on a registered device, such as via an app on a mobile phone. Using 2FA means customers can rest assured that any potential rogue users with stolen usernames and passwords will still be denied access. Easy company-wide set up The initial set-up for company-wide use of 2FA within Integriti can be completed within a few minutes by activating 2FA and adding it to a security policy that makes 2FA a requirement for system operators. Operators are then asked to enroll in 2FA at their next login. For this, they are prompted to scan a QR code using a compatible authenticator app on a mobile phone or other device, and enter the 6-digit code provided. Enrolled operators need to enter the code provided by the authenticator each time they login. The codes time-out after 30 seconds to ensure maximum security. If anyone forgets their phone or device needed to generate 2FA codes, a system administrator can...
I’m going to start blogging more about detection of protocol/app anomalies, detection of lateral movement and/or data exfiltration, and more. For many years I have been watching users and applications furrow their way across networks and I’m gonna start data-dumping that info here 🙂 But…first…I manage a web server for a friend. It occurred to me that machine-learning could be useful in alerting when an attack is under way. I took the following steps 1) Get as much data as possible for this device. For Apache, this just meant gathering all the log files. 2) Parse the data and, for each session, look at the path taken as the user or bot perused the server (Note: outside of my initial scope, but timestamps are useful here to weed out a user versus a machine). 3) So, an average session will look like R1->R2->R3->RX where each “R” is a request. So R1 could be index.html, R2 could be “Contact Us”, R3 could be “contact_form.php”, etc. I started using Markov to build a model; however, instead, I took each set of 2 and initialized those values…e.g. S={R1->R2,R2->R3,R3->RX}. For the next session I might have S={R1->R5,R5->R3,etc.}. At the end of all the parsing, I have a big set of all state transitions possible for each R. So, given RX, there are a finite number of R states that RX can transition to. 4) For each of the R states, I now re-parse the log file and find the number of transitions. This is a matrix that shows the number of observed transitions from RN to every other R state. So, for instance,...
“There’s time, though not unlimited time, to get the job done. We must make a continuing public commitment to securing cyberspace — and we must do so now.” – Melissa Hathaway Cyber Security Expert and President of Hathaway Global Strategies, LLC On June 10, the McCain Institute for International Leadership at Arizona State University hosted Chris Brose, author and former policy adviser to Senator John McCain, to discuss his book, “The Kill Chain: Defending America in the Future of High-Tech Warfare.” During the discussion with former Director of the National Counterterrorism Center Nick Rasmussen, Brose emphasized the need for American focus and investment in cyberspace and cautioned against risking “calamity and crisis” that could occur absent addressing American cybersecurity vulnerabilities. Brose’s passionate call to action pointed out that our ever-increasing dependency on technology, while greatly enhancing our society, has created systemic risks that require urgent attention. We must be clear-eyed – safeguarding our society from cyber security issues is very complex. Without significant mitigation of these risks, we will see more and more disruptive and damaging cyberattacks that have the ability to greatly impact our day-to-day lives. Protecting our national security, our commercial interests and the security and rights of our civilians is a highly complex task. According to the United States Cybersecurity and Infrastructure Security Agency, there are 16 critical infrastructure sectors. Some of these include commercial facilities, critical manufacturing, chemical, communications, dams, emergency services, financial services, food and agriculture, energy, healthcare and public health. Cyberattacks on these sectors present extreme risk and the fallout from attacks on any one of them could cause long term damaging consequences....
AUSTIN, Texas — The National Science Foundation has selected The University of Texas at Austin to lead the NSF AI Institute for Foundations of Machine Learning, bolstering the university’s existing strengths in this emerging field. Machine learning is the technology that drives AI systems, enabling them to acquire knowledge and make predictions in complex environments. This technology has the potential to transform everything from transportation to entertainment to health care. UT Austin — already among the world’s top universities for artificial intelligence — is poised to develop entirely new classes of algorithms that will lead to more sophisticated and beneficial AI technologies. The university will lead a larger team of researchers that includes the University of Washington, Wichita State University and Microsoft Research. “This is another important step in our university’s ascension as a world leader in machine learning and tech innovation as a whole, and I am grateful to the National Science Foundation for their profound support,” said UT Austin interim President Jay Hartzell. “Many of the world’s greatest problems and challenges can be solved with the assistance of artificial intelligence, and it’s only fitting, given UT’s history of accomplishment in this area along with the booming tech sector in Austin, that this new NSF institute be housed right here on the Forty Acres.” UT Austin is simultaneously establishing a permanent base for campuswide machine learning research called the Machine Learning Laboratory. It will house the new AI institute and bring together computer and data scientists, mathematicians, roboticists, engineers and ethicists to meet the institute’s research goals while also working collaboratively on other interdisciplinary projects.

Cyber security is one of the most talked about subjects in the technology field. Having your business data secured is crucial, but there are ways to stay protected. We’re here to help you keep your data protected with these security practices we should all do to ensure cyber security! Changing Passwords/Password Strength Password safety cannot be stressed enough! Changing your passwords every 60-90 days will allow your information to stay protected. With that, your cyber security will continue to increase. Not only will changing your password help, but also make sure it is STRONG. Adding symbols, numbers, and making sure the length is 8 or more characters will help keep the password strong. In the example presented above, pa$$word1a has a stronger password strength than password1 (please don’t use example above for your next password). Webroot has given some greats tips for creating a new password. Using a phrase and incorporate shortcut codes and acronyms will keep the password strong while being able to remember your favorite phrase or saying. Some examples are 2BorNot2B_ThatIsThe? (To be or not to be, that is the question) or ABT2_uz_AMZ! (About to use Amazon). Unique passwords are harder to break through than weak and simple passwords (please do not use any examples given above). When selecting a password, do not use any personal information! Using personal information can lead to hackers knowing the answers to your security questions. Examples of personal information to not use: Your name Age Date of birth Child’s name Pet’s name Favorite color/song Don’t Use The Same Password For Everything! Using the same password for multiple logins will cause a bigger...
