While cyber-attacks and intimidation are an ongoing battle, they can be prevented by recognizing the various types of contracts, exploits, tools, and resources used by malicious players. In addition, knowing where to expect and how to attack ensures that a company creates security measures to protect the systems.
Cyber-attacks are an evolving threat, and 350,000 new malware signatures are received every day.
Today’s business perimeter includes cloud and portable and remote assets, and there may be hidden assets that the company is unaware of. There is no complete security protection, and the dignity of IT means that no company can record all the assets it There is a growing challenge of protecting many assets that may not be recorded, and CISOs are looking for ways to maintain their security.
One way out is to collect and classify assets in such a way that the protection process deals with perimeter vulnerabilities and visibility.
Map the Internal Paths
A company’s system is immensely complex. So for an attacker, trying to understand the whole attack surface is a hopeless case. The attacker won’t need to know all the assets and everything about the security strategy. So they aim for the most vulnerable target as an entry point to crack an attack surface.
Analyzing these points, a company can make a strategy to protect the system. They need to find the path between the attack surface and their sensitive assets, and eliminate it.
Categorize Assets for Cyber-Defense
There are endless ways to break it down into categories, and these should depend entirely on the context of the organization
The company should try and train employees to group assets into functional groups. They should look at what represents the “path” of the attacker, and then decide how many policies a company should create around them to ensure security.
Chances are, the most of the internet-facing assets are components of software-as-a-service (SaaS) apps or appliances that are not in use or don’t need to be used. If a company uses the VPN only when it has an appliance that provides file transfer and VPN, they should turn off the file-transfer feature.
The trick is to shut such features down and forget about them. If an employee requires it to get the job done, it is easy to turn it back on.
Narrow down the priorities and work on that
Most companies probably have established DMZs on their network. It is where the goods are stored, that need to be accessed online and carefully monitored. The business website stays on the server itself which is completely separated from the main business. DMZ is where the most difficult isolation and monitoring could be accessed.
Anything in DMZ is intentionally used with minimal rights, and by being in DMZ (or even deep in the network), any service gains segmentation, visibility or surveillance. There are easy but crucial ways to get into the layers. Each deeper layer in the area should gain more protection, and we need more failure in order to break the law.
Dividing and strengthening reduce the opponent’s options. Limiting normal activity between assets where possible (such as between DMZ and the core network) creates opportunities for acquisition.
A company must design their defense systems taking into account that the attacker may infringe on any property and have its controls, rights and operations. Any company can protect their assets by practicing deep defense – knowing what’s important, and implementing various controls without a single point of failure.
