How to protect your network from advanced hackers?

To prevent advanced hackers from doing anything else, organizations and governments can use application whitelisting. Most organizations have assets that should be protected and segmented off from the rest of the network. Whitelisting applications helps prevent attackers from running malware or something unusual on those business-critical assets.

Which is the best way to defend against network intrusion?

To further foil the plans of nation-state hackers, defenders can develop a baseline for “normal” behavior, make use of network logs and follow best security practices such as by setting the least amount of privileges for accounts, segmenting off parts of the network and whitelisting applications. 3. Establish Persistence

How are attackers able to establish persistence in the network?

Attackers who achieve initial exploitation ultimately seek to establish persistence in the network. They commonly do so by escalating privileges, finding the Run Keys or getting into scripts. To prevent advanced hackers from doing anything else, organizations and governments can use application whitelisting.

What should be the focus of network security?
