![]() This might include computers or Internet connections that seem unusually slow, unexplained activity during off hours, files being renamed, moved, or installed without reason, or irregular outgoing data.Ĭybersecurity employees will also need training to understand the significance of these warnings. Modern breach detection software can look for larger patterns that might signal a more significant threat, and then deliver security alerts that highlight the most suspicious activity. Employees whose job it was to monitor these reports quickly found themselves lost in a sea of alerts without many good ways of differentiating the real threat from the many false alarms. Old malware detection software tended to deliver incident reports that were poorly organized and contained little prioritization. Fortunately, newer software can deliver information about sustained attacks in a manner that is easier for your security team to prioritize and interpret. The tools you use to detect a cybersecurity breach will be critical in mitigating the threat before it spreads through your system. You might deter some burglars, but the determined thief can break in and be long gone before you notice. ![]() Proper encryption, firewalls, and access controls between networks can also prevent a weak point in the system from spreading.īut without breach detection software, all these measures are like locking your door and leaving on vacation without enabling your security alarm. And, of course, Equifax’s failure to detect the security breach for over two months gave the hackers extra time to gather and use the data with no one the wiser.Īnyone familiar with the WannaCry hack will recognize the theme of malware exploiting a flaw in software that hadn’t been updated with the appropriate security patch. The data leak was made worse by Equifax’s poor system segmentation and inadequate encryption of sensitive data. Although Apache Struts had released a patch in early March to address this weakness, Equifax still had not installed the update by the time their network was compromised in May. ![]() The initial hack targeted a flaw in the Apache Struts web applications. There were several factors which lead to the Equifax security breach. The full ramifications of this breach on those affected are as yet unknown, but the stolen information is enough to fuel untold cases of identity fraud. In that time, hackers stole personal information for over 145 million United States consumers, and potentially the data of several million more consumers in the U.K. The Equifax data breach began in mid-May, 2017, but was not detected until July 29th-a full two and a half months later. What you can learn from the Equifax breach. This is one of the key lessons of the Equifax breach, which provides an excellent case study of all the things that can go wrong in a massive security leak. You also need systems in place that will monitor your network and alert your team to unusual activity. ![]() The longer it can remain hidden within your system, the more information it can leak to its creator.īecause of this, it isn’t enough to have strong safeguards in place against a security threat. But malware that is designed to steal your data benefits from remaining undetected. Once it has propagated, it initiates the encrypt-and-ransom sequence which makes it so dangerous. Ransomware usually only remains hidden on your network long enough to spread itself to other areas of your system. While ransomware can grind your business to a halt by holding your data hostage, there is one way in which it is less dangerous than other malware: it makes itself known right away. We wrote last week about the threat ransomware poses to your business, and strategies you can use to prevent your system from being compromised. No cybersecurity defense is complete without breach detection and a response plan.
