Cybersecurity: Be Prepared for Modern Day IT Threats

March 21, 2012

Digital communications and online activities are so prevalent today that they’re essential to business success. Unfortunately, digital opportunities also bring the potential for digital information threats. CPAs – as business owners, employers and employees, advisers and planners – are in a position to help protect businesses and clients. Make sure you are thoroughly versed in the latest developments on cyber security and industry best practices for deterring and combatting the viruses and scams that can confuse clients and customers and, in some extreme situations, ruin IT systems.

Everyone is susceptible to cyber attacks. In the past several months, “phishing” scams have been aimed at the Internal Revenue Service, the Vatican, the Better Business Bureau, Fox Broadcasting Company, Sony Pictures Entertainment and the AICPA. In the recent email scam using the AICPA logo, please note our systems were not compromised and we are working with law enforcement to investigate the source of the fraudulent email. Below are several resources to educate you on securing your systems and personal information.

Through its Information Technology member community, the AICPA has long been developing resources to guide members and others on cybersecurity measures. Here are a few of them:

The federal government and its agencies have gotten involved in cyber threats as well. Following are related articles:

Fast Facts

According to a January 2012 report by EMC Corporation/RSA:

  • Throughout 2011, financial institutions comprised more than half of the entities targeted for phishing

Best Practices to Stay Safe

Symantec Corporation is one of the leading providers of cyber security products and services. Below are some of its recommendations to help avoid cyber attacks, ranging from malware to phishing:

  • Regularly update antivirus, firewall, intrusion detection and intrusion protection solutions.
  • Keep software patches up to date, especially on systems that host public services and are accessible through your firewall.
  • Configure mail servers to block or remove email that contains attachments that are commonly used to spread viruses.
  • Train employees to not open attachments unless they are expected and come from a trusted source, and to not execute software that is downloaded from the Internet unless it has been scanned for viruses.
  • Do not provide personal information such as user IDs, account numbers or passwords in response to an email, even if the e-mail looks legitimate.
  • Do not click a site link from within an email. It is best to open a new Internet browser and type the address directly.
  • Consider the possibility of restricting Internet use by employees, specifically shopping, as they are opportunities to compromise the network.
  • Have emergency response procedures in place, including back-up and restore capabilities in order to restore lost or compromised data.
