Increase Network Security with Better Threat Visibility

RSA-NetWitness-Infographic-Visibility(1).jpgCybersecurity should be a priority for any organization. With a new cyberattack launched every 39 seconds, there is little hope for any organization to fly under the radar, no matter how small it is.

That's why detection and awareness of changing and evolving threats is so important. First, let's look at why basic protocols are helpful but not enough in thwarting attacks.

If you approach cybersecurity like most businesses, you probably use security logs as your primary line of defense. Security logs are crucial for any good cybersecurity system, but alone they are not sufficient.

Mere Detection Does Not Prevent Infiltration

Security logs contain valuable data to keep your network safe, but there are two main shortcomings:

  • Security logs won't protect you from an ongoing attack.
  • These logs only tell you when a known threat has been detected and neutralized.

In other words, security logs will tell you when your anti-virus blocked malware, but won't protect you from someone using stolen credentials to harvest data or from a new variant of malware. You can review data linked to an attack after your network is compromised, but can't effectively protect your data from hackers in the first place.

Improving network security should be an ongoing priority because hackers constantly come up with new ways to launch attacks against businesses. Further, emerging technologies like the Internet of Things and cloud computing make your data more vulnerable.

Beyond Security Logs

Making your network safer starts with increasing threat visibility. This strategy expands and refines your view of what happens on your network, simplifies threat identification, speeds up real-time responses, and uses data to improve those responses and, ultimately, your network security.

Ideally, you should collect information from several sources, including your security logs, endpoint data, and network packets. Your system should then correlate the data so you can see what happens on your network in real time.

Threat visibility does not stop here. You can make your network safer by using analytics to detect unusual behavior, such as a user intentionally or unintentionally compromising the network, for instance, by following a link sent in a phishing email.

A cybersecurity report compiled by Wombat Security showed that 85 percent of organizations were victims of phishing attacks in 2015. And while user education helps, it is not a good defense since 30 percent of phishing emails are opened.

This is precisely why you need to focus on threat visibility. This approach protects your network from phishing attacks, new malware, user mistakes, and other threats. It prioritizes how you fight off threats.
