Recent large-scale cybersecurity incidents have highlighted the need for increased vigilance and defense against information security threats that affect organizations worldwide. Hackers stole the personal data of more than 21 million people in the Office of Personnel Management (OPM) Breach in 2015. These cyber-attacks resulted in the theft of personal information of millions of Americans, many of whom are current or former Federal workers and contractors. Stolen information enables hackers to conduct individual targeted cyber-attacks, such as spam and phishing campaigns. Individuals, businesses, and other organizations must stay aware of emerging threats and act quickly to secure their data and networks.
