As Mark MacCarthy, SIIA VP of Public Policy, wrote in a column last week, when it comes to Cybersecurity: Sharing is Caring!  Information sharing on known cyber threats and vulnerabilities is the most critical component to prevent and mitigate attacks. When a company detects a breach, a crucial next step is to immediately let other companies and government agencies know about it right away. If one company is under attack, it is likely that other enterprises and institutions are also vulnerable. But without timely warnings, organizations have no ability to prepare their own defenses and team up to prevent the spread of attacks.
