In the past, vendors and hackers gave different names to the same vulnerabilities. One company might package a group of five vulnerabilities into a patch or service pack and call it by one name, while another vendor might call the same group by five separate names. This confused IT decision makers who evaluated security products. It was difficult to compare scanning and intrusion detection tools because the vulnerabilities and exposures that they checked for had different names depending on the vendor's naming conventions. Fortunately, MITRE is changing that. MITRE, a non-profit systems engineering corporation, has created a standard Common Vulnerabilities and Exposures (CVE) list. Thanks to the CVE list, you can now evaluate three security vulnerability scanners and ask, "How many CVEs does the tool cover?" and have a valid basis for comparison. When one of MITRE's trusted data sources discovers a potential CVE entry, MITRE's CVE editorial review board assigns it a candidate name and number. The CVE editorial review board then reviews the candidate to make sure it is not already a candidate or a live entry, and then votes whether to accept it as a CVE entry. MITRE's CVE editorial review board consists of security experts from not only MITRE, but also the broader security community, and includes experts from security consulting companies that are not aligned with any vendor or product. All security vendors should adopt MITRE's nomenclature. There is no fee for obtaining the CVE list, and in fact you can download the entire list with a click from MITRE's site. With no other competing nomenclature standards for common vulnerabilities and exposures, MITRE's list is the end all and be all of common vulnerability and exposures for system and network security. The CVE list makes it easier for security vendors to develop intrusion detection and scanning tools. As more IT decision makers understand the meaning of CVE, products with CVE-compatible names will likely receive a better reception on the market. According to Marcus Ranum, CTO of NFR Security, a leading maker of intrusion detection products, "It's critical to have all IDS products report detected vulnerabilities using a common language. That way product 'A' doesn't tell you it's found a 'SYN flood attack' while product 'B' tells you it's found a 'SYN denial of service'-- it saves time for the end customer who needs to correlate information." For network managers, products that contain CVE-compatible names make it easier to handle day-to-day security issues. Security administrators can find out and tally how many entries on the CVE list they have covered. Some products currently containing CVE-compatible names include: - NFR's IDS - PentaSECURITY's Siren(IDS) - Qualys' QualysGuard - ISS' Internet Scanner - Symantec's Enterprise Security Manager - BindView's HackerShield - PGP's CyberCop Scanner Moving forward, one of the biggest challenges for MITRE will be quickly classifying new CVE entries. According to MITRE, today there are 1,510 CVE names. With new vulnerabilities being found every day, a speedy review and naming process is crucial. MITRE's CVE development has been instrumental in untangling and verifying the wacky jargon of security vulnerability names, and all eyes are on them to lead the way in managing this complicated process.
