26 Mar Why is Vulnerability Management Important?
Vulnerability management is an essential part of securing your organization. By adhering to the best practices for vulnerability management, you can identify and control the risks that are inevitably inherent in any environment. But, if vulnerabilities are not properly managed, they can lead to problems, such as cyberattacks.
The following are some common vulnerabilities and how they can be managed.
Common Vulnerabilities and How They Can Be Managed
Weak Passwords
This is a major cause of data breaches in companies. Weak passwords and password reuse expose organizations to account takeovers, data breaches, and any other form of cyberattack. Passwords are regarded as weak if it is short, common and easily guessable. Vulnerabilities due to weak passwords can be significantly reduced by setting a long and complex password using a mix of letters, numbers and symbols, avoiding password reuse, using multi-factor authentication and hardware tokens.
Outdated/ Unpatched Software Applications
Outdated software exposes an organization to network security risks and system failure. Outdated software applicated have unaddressed bugs making them prone to security attacks. To ensure their software applications, most vendors have a team of developers that is constantly on the lookout for weak spots. New patches are then created to address the found bugs and are made available to users. To protect a company’s data from any breaches or shutting down of the system, it is absolutely necessary to install those patches constantly.
Lack of Data Backup
Preventing cyberattacks before it happens is essential. However, sometimes the attacker may be a step ahead of you, and you need to be prepared for this. For example, someone within the organization can inadvertently download ransomware, leading to data losses and shutting down of the whole system. Such a kind of vulnerability is addressed by having an offline backup and disaster recovery in place that is regularly synchronized. This ensures the data is safe and can easily be retrieved if lost, preventing downtime.
Poor Firewall Configuration
A firewall ensures a regulated traffic flow in and out of the network. Also, an administrator can set up rules that block security threats such as unauthorized access of the network and security threats. However, the effectiveness of a firewall depends on its configuration. Poor firewall configuration makes a network vulnerable. A firewall can be made stronger by eliminating configuration errors like typos and classification problems.
Why is Vulnerability Management Important?
Enhances Security and Control
Vulnerability management is not a one-time activity. It continues even after a risk has been identified and the threat nullified. Long-term vulnerability management ensures you are one step ahead of your attacker and at per with technological developments in the cyber security field.
Vulnerability management helps assess threats, their severity level and identify priority areas to prevent specific types of vulnerabilities. By consistently monitory the network environment of a business or organization, you feel safer and more secure.
Saves Money
Data loss and breaches can be pretty expensive and can bring a large company to its knees. Managing vulnerabilities is less costly than addressing the aftermath of a cyber-attack. Vulnerability management ensures a business does not reach the point of counting losses.
Immediate Fix of Vulnerabilities
Attackers only need to identify one source of weakness in a network to cause a breach. Vulnerability management ensures cyber security flaws are regularly identified and immediately fixed. Having a security flaw in a company’s network unaddressed for days, weeks or months greatly increases the chances of a breach.
Some vulnerability management solutions have automated patch management tools that scan software applications for missing patches and automatically download them. This helps in the immediate remediation of repeatedly occurring vulnerabilities in your network.
Reduces Downtime
A security breach can lead and often leads to disruption of business operations. The impaired productivity consequently leads to a loss of revenue. Constant vulnerability monitoring helps detect and fix risks early on, thereby saving the business time. Addressing a vulnerability is easy and fast compared to addressing a security breach.
Ensure Regulatory Compliance
Most organizations are required to have vulnerability management systems in place by regulatory bodies. In addition, the regulatory bodies ensure the organizations are in compliance and industry standards are met, such as ISO 27001, Information Security Management Systems (ISMS). ISO 27001 guides organizations and businesses, small or big, on how to manage their network vulnerabilities and assess and manage information security risks.
