This length of time can prove invaluable as it can give admins more time to detect the malicious activity before any real damage can be done. Changes like moving the “location” of the target data or moving segments will require a longer period of time for attackers to find the targeted data. If the threat actors attempt to enter the network using the old method, it will be flagged by the new(er) security policies put in place. If the targeted organization changes the network topology, the attackers’ gained knowledge will become useless to their attacks.
Since it also refers to how these devices are connected, network topology also includes passwords, security policies, and the like. The term refers to all devices connected to a network, be it the computers, the routers, or the servers. Network topology refers to how devices are connected within a network, both physically and logically.
To protect an organization from targeted attacks, changing the network topology should also be considered. It’s not enough to change passwords and remove the malware. In this article, we want to tackle how network topology can aid in defending the enterprise network from risks posed by targeted attacks. But since attackers are aware of the topology, they can try new ways to gain access easily without being noticed. Often times, efforts to thwart existing and prevent new attacks involve removing the malware and monitoring for network activity. They can use this new-found knowledge even after their attempts have been discovered.

They also now have the latest network topology, password sets, and security policies. They are now aware of existing security weak points, firewall rule setting flaws, and the wrong security equipment deployment. The lateral movement allows the attackers information they can then use to their advantage. The goal is to find more confidential information and find a stealthy method of access. In this stage, attackers will perform port scans, services scans, network topology mapping, password sniffing, keylogging, and security policy penetration tests. Once inside, the attackers will begin the lateral movement stage. These will then be used as lure for phishing emails, which inevitably result in gaining access in the targeted organization’s network. They may gather data such as email addresses, IP ranges, and contact lists. They need to gather information in the early stages to know the target they may gather information from various sources of intelligence, like Google, Whois, Twitter, and Facebook. When it comes to targeted attacks, attackers are not omniscient.
