The smaller the window of vulnerability, the smaller the chances are that a zero-day exploit will damage a network's systems. Checking for patches on a regular basis, preferably daily, will minimize the chance that attacks will get through. If system managers do this on a regular basis, they don't have to wait for an exploit to hit the news.
Scanning for vulnerabilities will make sure no patches are overlooked. If a known vulnerability exists, the chances are good that a fix for it is available.
Patching isn't the only defense, though. A well-protected network is safe against a broad range of unknown threats as well as known ones. Internal and external malware monitoring will detect attacks that have gotten through, allowing prompt removal. External monitoring of a website detects threats such as malicious JavaScript, altered pages, and unexpected redirects. Internal monitoring spots altered files, outgoing spam, and attempts to communicate with command-and-control servers.
Employee education is important. Many exploits depend on getting users to visit websites or open attachments that are tailored to the vulnerability. If employees recognize and discard phishing messages, the exploit might find no opportunity to cause trouble.
A Web application firewall (WAF) blocks suspicious traffic, keeping exploits from reaching their targets. Quttera's WAF uses behavior-based analysis, so it isn't limited to detecting known threats. It is constantly updated to be prepared for many kinds of hostile packets. The WAF is part of Quttera's comprehensive
