Cybersecurity Deep Auditing is an internal audit of logged activities across a network to ensure security strategies are compliant with regulatory agencies and working at peak performance. Auditing detects and prevents fraud by analyzing activity logs for suspicious behavior.
Too many organizations today believe that things like anti-malware or anti-viruses are all it takes to ward off cyberattackers. But last year, global companies were hit hard by a number of malicious attacks, like the WannaCry ransomware, despite spending $86.4 billion on cybersecurity. Cybercrime is on the rise, and is expected to hit companies with $6 trillion in damages by 2021. As organizations realize the need for greater, comprehensive security across their networks, cybersecurity spend will increase to a trillion dollars over the next few years.
What many people fail to realize is that nearly 80% of security breaches can be prevented with the right cybersecurity measures in place. But anti-viruses simply won’t cut it. Comprehensive defense strategies are needed to break the cruel cycle of cybercrime. Enter activity logging and deep auditing.
Why cybersecurity deep auditing matters
Cybercrime (and spend) is on the rise. Even if you have a strategy in place, the best way to prevent an attack is by ensuring all your cybersecurity dollars are performing effectively. Deep auditing reveals lapses or broken points in your security strategy that could easily go unnoticed otherwise.
In the event that other cybersecurity measures fail, third-line defense measures ensure that no activity slips by unnoticed, and that they remain compliant with regulatory agencies.
How does deep auditing (and activity logging) work?
Activity logging ensures that attackers are held accountable by providing an archived history of timelines and associated movements through the network. Logging keeps suspicious activity above the radar, and provides audit trails in the event something goes wrong. But logging activity isn’t the fix-all solution.
Deep auditing analyzes the activity happening on a network. Rather than simply leaving detailed accounts unseen, it scrutinizes them for lapses and suspicious trends to ensure that cybersecurity systems are working at peak performance. When red flags are detected, or unauthorized users access parts of the network, a security response is initiated.
But not all activity log management solutions equal log security. And attackers know this. Logs can be tampered with or destroyed in the event of system failure. While activity logs are never 100% tamper-proof, experts recommend storing encrypted logs on centralized log management systems rather than on local machines. This can help maintain the truest view of what’s happening in their systems. The best deep auditing services and policies track active-allowed and inactive-blocked accounts. They safely and effectively archive logs in an offsite centralized server to minimize the risk of log tampering.
How it fits into a comprehensive cybersecurity strategy
Even the best systems aren’t foolproof. That means it’s important to cover all bases. IT cybersecurity is vital to keeping your business up and running. Auditing activity is a vital third-line defense tactic to ensuring all systems and controls are up and running. Once systems are protected against internal and external breaches, deep auditing can ensure that security controls remain compliant.
