Black Hat hackers have evolved their strategies to target and attack enterprises with sophisticated cyber-attack techniques.
Enterprises today need to be extra vigilant about Black Hat hackers and their malicious intentions to infiltrate the IT infrastructure and accomplish their evil goals. Such cybercriminal troops infiltrate the business network to steal confidential information, and sell it on the dark web or simply disrupt the workflow.
CISOs should consider designing and implementing a robust security strategy that fills the gaps in the vulnerabilities and notifies suspicious user behaviour on the network to protect the enterprises from the Black Hat hackers. Here is how businesses can prevent cyber-attacks caused by Black Hat hackers.
Execute a vulnerability assessment on IT infrastructure
An initial step is to creating a robust cybersecurity plan is to perform a vulnerability assessment on the entire business network. It is one of the most effective ways to understand the weaknesses in the infrastructure, which the Black Hat attackers can bank on and exploit efficiently. This is not a one-time task; enterprises need to regularly perform vulnerability scanning to ensure the network is always secure.
Integrate advanced firewalls
Robust firewall solutions are an effective way to safeguard businesses’ network perimeter by protecting them from both internal and external cyber-threats. Advanced firewalls filter the network traffic and offer deeper packer inspection that detects and blocks malware and other severe security threats. CISOs should consider adopting a firewall to drop particular packets based on the packet’s protocols, source address, or destination address. An efficient Web Application Firewall (WAF) assists organizations in protecting their web apps from known and zero-day threats.
Embrace intrusion prevention systems
Embracing tools like Intrusion Prevention Systems (IPSs) in the security tech stack will assist organizations in identifying potential network or server intrusions and performing pre-configured actions to mitigate the attacks. Once the IPS solutions identify an attack in the process, they are capable of shutting down the network’s internet connection or the targeted server. There are chances that IPS generate noise, but it is better than having an underlying risk on a critical server.
Implement content filters
SecOps teams should consider implementing content filters in their IT infrastructure for the business users to restrict or grant access to particular websites or categories of websites. Black Hat hackers bank on users that visits malicious websites owned by them to download malware on the network that serves as the entry point for the attacks.
There is a high possibility that the server machines are executing useless but vulnerable services, which Black Hat hackers can exploit to infiltrate the network. For instance, insecure services like File Transfer Protocol (FTP) or telnet services. CISOs should consider eliminating all the unnecessary unsecured services to minimize the attack surface areas that Black Hat hackers can exploit.
Design and set stringent computer use policy
Setting stringent computer usage policies is an effective way to strengthen the organization’s system network. CISOs should consider drafting computer usage policies that define how users should use the computers, email, and the internet. Additionally, organizations should educate the workforce on the consequences of policy violations. Setting stringent computer use policies and consequences for violations will help minimize the risks of being a victim of a cyber-attack.
