In the evolving digital world, cyber attacks have become an alarming concern.
A cyber attack is an attempt to disable computers, steal data, or use a breached computer system to launch additional attacks, employing methods like malware, phishing, ransomware, or a man-in-the-middle attack. This blog post thoroughly explains cyber attacks and outlines seven key strategies that organizations can employ for protection.
Decoding different types of cyber attacks
- Malware: This is malicious software, including spyware, ransomware, viruses, and worms, that breaches a network through a vulnerability, typically installed through a risky link or email attachment.
- Phishing: A method of sending fraudulent communications that appear from a reputable source, phishing aims to steal sensitive data or install malware on the victim’s machine.
- Man-in-the-middle (MitM) attack: Attackers insert themselves into a two-party transaction, intercepting the traffic to filter and steal data.
- Denial-of-service attack: These attacks fill systems, servers, or networks with traffic that exhaust resources and bandwidth, making the system incapable of fulfilling legitimate requests.
- SQL injection: This occurs when an attacker inserts malicious code into a server that uses SQL, forcing the server to reveal information it normally would not.
- Zero-day exploit: This attack hits after a network vulnerability is announced but before a patch or solution is implemented.
- DNS tunneling: Malicious reasons for using DNS Tunneling VPN services include disguising outbound traffic as DNS and concealing data that is typically shared through an internet connection.
Understanding what happens during a cyber attack
Ways to prevent cyber attacks
- Use multi-factor authentication: Ensuring multi-factor authentication for all internet-accessing applications in an organization heightens security, making unauthorized access difficult.
- Create robust internal controls: Revoking system access for employees, contractors, and vendors who leave the organization ensures greater security and prevents potential problems in the future.
- Manage third-party security: Tight security controls, identifying potential cyber threats, and network monitoring are crucial to ensure system security when vendors or third parties access organizational systems.
- Educate organizational employees: Regular cybersecurity awareness training and education about phishing can significantly improve business security.
- Create data backups: Regular backups of important business data can keep a business strong and prepared for worst-case scenarios.
- Keep entire systems updated: Running the latest software and systems keeps data more secure and guards against potential security threats.
- Install antivirus software and a firewall: Protect your systems from security breaches by regularly updating and maintaining antivirus software and firewalls.
