How to Protect Your Business from a Cyber-Attack

Cross Posted from ITProPortal

In today's digital world, cyber attacks are inevitable and businesses must protect themselves accordingly.

Cleanrooming Legacy Systems

The WCry worm threw into sharp relief how quickly the turnaround between exploit announcement and the use of said exploit in a high-profile attack can be: a vulnerability patched in March, with a public exploit shown in April, was used worldwide in early May.

Network Segmentation

Network segmentation is the practice of dividing a formerly 'flat' network [where every device can contact every other device] into a series of segments that have restricted communication between them.

Egress Filtering

Egress filtering counteracts situations when the attacker is either seeking to sniff internal traffic that may be leaking outside the gateway or to provide a block against [and potentially notification of] so-called C2 traffic generated when an attacker has succeeded in infecting a system. Once egress filtering is put in place, your network will be far safer, and a much harder target for most attackers.

It is this specific antique practice that is directly responsible for the existence of the record-breaking denial-of-service botnet recently used to censor Brian Krebs and the similar attack on OVH - these botnets only exist because default credentials were implemented on devices, in flagrant violation of best-practices when building appliances.

Password Paste Prevention: Security Friend or Foe?

Password managers help secure the sites that allow them to be used – providing protection from both their own users, who historically choose weak credentials when forced to memorize them, and from the users' other accounts on other sites that might have been breached.
