How to Prevent Attack Vectors from Compromising Your Network

Cybercriminals have you in their crosshairs. These persistent threat actors want to infiltrate your network to steal data, commit fraud, and disrupt operations. The costs add up quick ─ the average data breach now exceeds $4.35 million.

To break in, hackers exploit vulnerabilities through attack vectors lying in wait within environments. Don‘t let them catch you defenseless. Arm yourself with knowledge to thwart their advances.

This comprehensive 2800+ word guide examines attack vector techniques and proven methods to shield against them. Follow these best practices and send hackers packing from your network perimeter.

What are Attack Vectors and Why Care

Attack vectors provide pathways for unauthorized users to slip past defenses and infiltrate networks.

💡 Attack vectors describe the various routes and techniques adversaries take to compromise environments.

Once inside, they install malware, destroy systems, steal data, and wreak all kinds of havoc. Attack vectors allow them to exploit weaknesses and process vulnerabilities.

📉 Alarming Stat: Cybercrime costs the world $6 trillion annually, the third-largest economy behind U.S. and China according to Cybersecurity Ventures.

Common attack vectors include:

  • Phishing: Deceive victims via email to download malware or unveil sensitive data
  • Weak Passwords: Crack credential passwords through brute force guessing
  • Software Bugs: Exploit undisclosed flaws to gain unauthorized system access
  • Brute Force Attacks: Barrage login portals with password guesses until successful

However, the term attack vector often gets misused in place of attack surface. While they may sound alike, clear differences exist.

Attack Surfaces vs. Vectors

Attack Surfaces represent the total area of vulnerabilities providing targets for nefarious actors to exploit.

Attack surfaces consist of software flaws, unpatched systems, and network misconfigurations. They encompass all explorable security deficiencies across an environment ─ known and unknown.

📉 Stat: 97% of organizations admit to having attack surface blind spots.

Attack vectors describe the specific pathways allowing unauthorized access through defenses. While attack surfaces denote the total vulnerabilities, attack vectors represent the entry points to target those weaknesses.

How Do Attack Vectors Work

Attack vectors provide openings for infiltrating otherwise secure systems. Threat actors utilize them to circumvent defenses and compromise networks:

  1. Adversaries detect potential targets through reconnaissance like port scanning.

  2. They gather information to map out vulnerabilities. Common methods include phishing attempts, social engineering, and malware.

  3. With weaknesses revealed, hacking tools get built to exploit them.

  4. Utilizing their toolkit, attackers gain initial access to install further malware, create backdoors, or exfiltrate data.

  5. Finally, hackers leverage their unauthorized access for profit through data theft, cyber fraud campaigns, and system destruction.

Stolen Credentials Fuel Attacks

The human element acts as the common linchpin in these intrusions. Over 80% of breaches originate from stolen credentials or social engineering attacks according to Verizon‘s 2022 DBIR report.

Weak passwords, reused credentials and susceptibility to phishing elevate risk of incidents. Users hold the keys to protected data and systems. And when coerced or careless, end up ushering attackers inside.

Now that you understand how cybercriminals slip through defenses, let‘s explore the most prevalent attack techniques.

Major Types of Attack Vectors

Diverse attack vectors enable breaches across digital environments:

Network-Driven Attacks

The network-based attack vectors initiate from an external network or device. They include:

  • DDoS Attacks ─ Overload systems/websites by flooding bandwidth or resources
  • Phishing ─ Social engineering tactic to steal credentials via email
  • Man-in-the-Middle ─ Intercept data and communications traversing networks
  • Weak Passwords ─ Guess weak login credentials using brute force
  • DNS Cache Poisoning ─ Redirect domain requests to fake, malicious websites
  • Session Hijacking ─ Takeover active login sessions to assume user identities

Web App Attacks

These vectors target vulnerabilities within web-facing applications including:

  • SQL Injection ─ Insert malicious SQL statements to access or destroy databases.
  • Cross-Site Scripting (XSS) ─ Inject malicious scripts stealing data or session cookies
  • Path Traversal ─ Access restricted directories and files on web servers
  • Remote File Inclusion ─ Plant backdoor code into web apps to assume control

📉 Stat: Over 43% of scanned web apps contain known vulnerabilities.

Endpoint Attacks

Compromising device vulnerabilities provides access to broader networks:

  • Unpatched Software ─ Exploit publicly known vulnerabilities using automated scripts
  • Misconfigurations ─ Malform application settings to enable attacks
  • USB Sideloading ─ Plant malware payloads on connected USB devices
  • Supply Chain Compromise ─ Backdoor software dependencies before installation

Physical Intrusions

Sometimes adversaries access environments the old-fashioned way ─ by walking through the front door:

  • Onsite Social Engineering ─ Impersonate staff to gain building access and plant devices
  • Unsecured Assets ─ Steal devices, backups or sensitive paperwork from facilities
  • Insider Threats ─ Disgruntled employees misusing privileges or stealing data before departure

Multivector Malware

The most successful attacks chain multiple vectors as launch mechanisms for malware including:

  • Trojans ─ Malicious software masquerading as legitimate programs
  • Viruses/Worms ─ Self-replicating code transmitting between systems
  • Spyware ─ Track user activity and harvest sensitive data
  • Ransomware ─ Encrypt files until ransom gets paid

📉 Alarming Stat: Ransomware damage costs are predicted to exceed $30 billion by 2023.

Now that you know how adversaries break in, let‘s explore proven security controls to halt them.

Securing Against Attack Vectors

Protect your organization through layered cybersecurity defenses:

Limit Access

Restrict access to only authorized users:

  • Least Privilege ─ Only provide minimal access to fulfill job duties
  • Multi-factor Authentication ─ Require additional credentials like tokens or biometrics to login
  • Principle of Separation of Duties ─ Ensure user actions require multiple parties to approve sensitive transactions
  • Network Segmentation ─ Isolate and containerize systems using VLANs and internal firewall rules

Harden Endpoints

Reduce endpoint attack surfaces through system hardening:

  • Continuously Patch Software ─ Apply latest security fixes for apps/OS without delay
  • Disable Unnecessary Services ─ Turn off unused network protocols and administrative tools
  • Enforce Application Whitelisting ─ Only permit vetted programs while blocking all others

📉 Stat: Unpatched software leads to [over 50% of breaches](https://www.whitehatsec.com/blog/fbi-alert– Indicates most-common-exploited-vulnerabilities/) according to an FBI alert.

Deploy Protective Layers

Install safeguards providing threat visibility and malicious activity alerts:

  • Endpoint Detection and Response ─ Uncover intruders that bypass perimeter defenses
  • Deception Technology ─ Deploy decoy servers, credentials and data to detect lateral movement
  • Privileged Access Management ─ Monitor and control administrative access across infrastructure

Provide Security Training

Educate staff to recognize social engineering techniques and cyber threats:

  • Simulated Phishing Exercises ─ Run mock attacks to improve detection rates
  • Teach Critical Thinking ─ Promote skepticism of unusual emails and webpages
  • Report Suspicious Activity ─ Encourage fast response when noticing odd network behavior

📉 Alarming Stat: Only 37% of phishing emails get identified as suspicious.

Following cybersecurity best practices fortifies your defenses against attack vectors. Now let‘s recap the key takeaways.

Key Takeaways

With cyberthreats growing daily, organization must vigilantly prepare against attack vectors by:

🔐 Understanding what attack vectors are and how hackers exploit them

🔐 Cataloging your organization‘s vulnerabilities comprising the attack surface

🔐 Implementing multilayered security controls like patching, endpoint protection and access management

🔐 Educating staff to identify social engineering attempts including phishing links

Remember adversaries rely on human error to bypass even robust defenses. Limit access to sensitive data, require complex credentials, establish data protection policies and train employees as the last line of defense.

Following cybersecurity best practices reduces risk and costs of dealing with data breaches. Don‘t allow your organization to become another statistic ─ stop attackers in their tracks by securing all intrusion pathways.
