Vulnerabilities and exposures are the building blocks of cyber-attacks. They open systems to attack, leading to some of the world’s most significant data breaches.
Effective risk management starts with understanding these weaknesses. A centralized list of vulnerabilities with CVE identifiers helps everyone stay informed and take appropriate action.
Vulnerabilities
Vulnerabilities are flaws in computer software, firmware, hardware, or service components that attackers can exploit to gain unauthorized access to systems and launch cyber-attacks. Attackers use these vulnerabilities to run code, infect systems with malware and other threats, steal data, or disrupt operations.
Vulnerability identification is the first step in the vulnerability management process. Once a vulnerability has been identified, it’s given a unique identifier called a Common Vulnerability Enumeration (CVE) name. CVEs allow cyber security professionals to reference the same information about a vulnerability across multiple sources, including security advisories and bug trackers.
CVEs help IT professionals coordinate and prioritize their efforts to resolve vulnerabilities and make their computer systems more secure. They also serve as a baseline for communication and discussion among all parties involved in vulnerability management.
Smaller companies had fewer medium- and critical-risk vulnerabilities than larger organizations. However, they were still more likely to take longer to patch and fix those vulnerabilities.
Despite the best efforts of security teams, human error remains a significant source of vulnerability types. Users can unintentionally leak information, for example, by sending a confidential document to the wrong person or leaving their laptop or mobile device in a public place where it could be stolen.
Exposures
Vulnerabilities and exposures are a big part of why companies must prioritize cyber security and take preventive measures. To help businesses understand these risks, the CVE Program provides a public database of information security vulnerabilities called the CVE dictionary, which offers a free resource to IT teams. The dictionary uses a standardized naming convention to help organizations monitor new threats and create baselines for evaluating cyber security tools’ effectiveness.
A vulnerability is a software, firmware, or hardware flaw that could give attackers unauthorized access to an organization’s computer systems. These weaknesses can be exploited to run code, install different types of malware and steal or destroy data. Using these weaknesses can lead to a data breach or ransom ware attack.
On the other hand, exposure is an attack that doesn’t involve direct access to a computer system. These weaknesses can be exploited to collect customer information, like passwords or credit card details, to sell on the black market or use for other malicious purposes.
Vulnerabilities and exposures are frequently discovered by software vendors, security researchers, and even end-users. They can then report these weaknesses to a CVE Numbering Authority, an authorized entity that assigns and publishes CVE records. These CVE programs include prominent software vendors, open-source projects, coordination centers, bug bounty service providers, and research groups.
Mitigation
Cyber security experts use mitigation techniques to reduce the risk of a vulnerability becoming exploited. Mitigation strategies include:
- Hardware and software changes and updates.
- Patching systems.
- Other tools to detect and respond to exploitation efforts.
As cyber-attacks continue to increase, businesses must continuously employ these mitigation techniques to keep their digital environments safe.
Organizations can use these tools to identify and correct their vulnerabilities as quickly as possible. For example, the CVE (common vulnerabilities and exposures) program is an open-source database that tracks known cyber security vulnerabilities. It provides an identifier for each vulnerability so that security professionals can access information about them from multiple sources.
The goal of the CVE is to allow cyber threat identification and response across all systems and applications. The program is supported by 240 CVE Numbering Authorities (CNAs), which are participants and partners in the CVE Program. These entities are responsible for assigning CVE IDs to new vulnerabilities discovered by the community.
The CVE program helps to speed up the process of mitigating vulnerabilities. It also allows for a more coordinated approach to addressing these weaknesses in computer systems worldwide. This is because many security advisories issued by vendors and researchers mention a CVE, enabling security teams to coordinate their efforts to make computer systems more secure.
Prevention
To thwart cyber-attacks, organizations should practice preventative techniques. These can include preventing employees from using insecure devices or applications, keeping software up to date, and monitoring new vulnerabilities. These prevention techniques also apply to other aspects of security, such as implementing firewalls and intrusion detection systems.
A vulnerability is a weakness that hackers can exploit to gain access to a system and the data it stores. Vulnerabilities can be used to run code, access memory, install different types of malware, and steal or destroy sensitive information.
When a vulnerability is discovered, it is added to the CVE database and assigned a unique identifier. This centralized list makes scanning for and identifying new threats easier for cybersecurity professionals. Each entry is given a specific name that includes the year the flaw was accepted into the CVE and a four-digit number. This standardized naming convention also allows for easily comparing vulnerabilities across different information sources.
The CVE is a free directory of public knowledge about computer vulnerabilities and exposures. It is maintained that operates federally-funded research and development centers in the United States. Developers must incorporate this database into their CI/CD pipeline to identify open-source libraries with known vulnerabilities and ensure their products are secure.
