Top 4 Methods Used to Attack Networks (And How to Defend)

In today’s interconnected digital landscape, cyber threats pose a significant risk to businesses of all sizes. Understanding the most common attack methods is crucial for implementing effective defense strategies. Here are the top four methods used to attack networks and how IGTech365 can help you fortify your defenses.

Phishing remains a persistent threat, relying on social engineering to deceive users into divulging sensitive information. Hackers craft convincing emails or messages that mimic legitimate sources, often urging recipients to click on malicious links or download attachments.

• Defense:
  • Employee Awareness Training: Regularly educate your workforce about phishing tactics, including identifying suspicious emails, verifying sender identities, and avoiding clicking on unsolicited links or downloading attachments from unknown sources.
  • Advanced Email Filtering: Implement robust email filtering solutions that employ AI and machine learning to detect and block phishing attempts before they reach user inboxes.
  • Multi-Factor Authentication (MFA): Enforce MFA for all user accounts to add an extra layer of security, making it significantly harder for attackers to gain unauthorized access, even if they have stolen credentials.

Malware, encompassing viruses, worms, ransomware, and other malicious software, can infiltrate networks through various channels, including malicious downloads, infected email attachments, and drive-by downloads. Once inside, malware can steal data, encrypt files, or disrupt operations.

• Defense:
  • Comprehensive Endpoint Protection: Deploy robust endpoint security solutions that include antivirus, anti-malware, and intrusion detection capabilities to protect devices from malware attacks.
  • Network Segmentation: Segment your network into isolated zones to limit the potential impact of a breach. This approach helps contain malware infections and prevents them from spreading to critical systems.
  • Regular Patch Management: Keep all software and operating systems up-to-date with the latest security patches to address vulnerabilities that attackers can exploit.

Brute force attacks involve automated attempts to guess passwords by systematically trying numerous combinations. While time-consuming, these attacks can be successful, especially against weak or easily guessable passwords.

• Defense:
  • Strong Password Policies: Enforce strong, unique password policies that require a combination of uppercase and lowercase letters, numbers, and special characters.
  • Password Management Tools: Use password management tools to generate and store complex passwords securely, eliminating the need to remember multiple passwords.
  • Account Lockout Policies: Implement account lockout policies to temporarily disable accounts after a certain number of failed login attempts, deterring brute force attacks.

DoS attacks aim to overwhelm network resources, making them inaccessible to legitimate users. By flooding servers with traffic, attackers can disrupt services and cause significant business disruption.

• Defense:
  • Web Application Firewalls (WAFs): Deploy WAFs to filter and block malicious traffic, protecting web applications from DoS attacks.
  • Network Intrusion Detection Systems (NIDS): Implement NIDS to monitor network traffic for signs of suspicious activity and alert security teams to potential threats.
  • Robust Network Infrastructure: Invest in a robust network infrastructure with sufficient bandwidth and redundancy to withstand increased traffic and potential attacks.
