1. Asset discovery

  • Gain visibility into your digital infrastructure and connected devices to address common cybersecurity challenges.
  • Determine the scope of your scanning efforts to effectively identify vulnerabilities and risks.
  • Overcome the challenge of limited visibility by understanding your organization's digital infrastructure.
  • Mobile Devices: Smartphones, laptops, and similar devices are designed to disconnect and reconnect frequently from the office, as well as employee’s homes and often other remote locations.
  • IoT Devices: IoT devices are part of the corporate infrastructure but may be connected primarily to mobile networks.
  • Cloud-Based Infrastructure: Cloud services providers make it easy to spin up new servers as needed without IT involvement.

2. Asset Prioritization

Prioritize vulnerability assessments based on budget constraints and resource availability. Assess the feasibility of conducting vulnerability assessments for all systems.
Some examples of where you may wish to priorities are:
  • Internet-facing servers
  • Customer-facing applications
  • Databases containing sensitive information
It’s worth noting that the two of the most common vectors for untargeted or mass attacks are:
  • Internet facing systems
  • Employee laptops (via phishing attacks)

3. Vulnerability scanning

Vulnerability scanners play a crucial role in identifying known security weaknesses. These scanners leverage publicly reported information about vulnerable software. The scanner examines and analyzes the responses received from the systems.
  • Open ports & running services
  • Software versions
  • Configuration settings
  • Vulnerability scanners excel at identifying numerous known vulnerabilities in the system.
  • The scanner utilizes specific probes to detect individual vulnerabilities.

4. Result analysis & remediation

  • Severity: In vulnerability scanning, labeling potential vulnerabilities based on severity is crucial. When prioritizing remediation efforts, it is important to address the most severe vulnerabilities initially.However, it is essential to avoid disregarding the remaining vulnerabilities indefinitely, as hackers often leverage multiple minor vulnerabilities to create exploits. A reliable vulnerability scanner not only identifies vulnerabilities but also provides suggested timelines for addressing each issue, enabling timely resolution.
  • Vulnerability Exposure: Public-facing systems, being more susceptible to random internet scans, require higher prioritization for remediation. Next in line are employee laptops with vulnerable software, followed by systems hosting sensitive data or those that could significantly impact business operations. Prioritizing vulnerabilities based on these factors ensures effective risk management.

5. Continuous Scanning

  • Conduct vulnerability scans regularly to keep track of vulnerabilities in your organization's digital infrastructure.
  • Recognize that a vulnerability scan provides a snapshot at a specific point in time, but vulnerabilities can change rapidly.
  • Establish processes for timely remediation of identified vulnerabilities to minimize the window of exposure.
  • Invest in automated vulnerability management tools and solutions to streamline and enhance your vulnerability management process.
  • Incorporate automated vulnerability assessments into your software development process for proactive vulnerability management.
  • Integrate vulnerability assessments into your continuous integration and deployment (CI/CD) pipelines to identify and address vulnerabilities early in the software development lifecycle.
  • Avoid the need for developing and shipping patches for vulnerable code by addressing vulnerabilities during the development stage.
