How Sarbanes-Oxley Affects Corporate Email Systems

The role of email in Sarbanes-Oxley compliance cannot be overstated. At a high level, email is the primary internal and external communication tool for corporations. However, a more granular inspection of email's role, especially as pertaining to corporate information security, reveals that it can make or break a company's efforts to comply with Sarbanes-Oxley. Email systems are critical to ensuring effective internal control over financial reporting, encryption of external messages and active policy enforcement, all essential elements of compliance.

Complying with Sarbanes-Oxley

The changes required to ensure Sarbanes-Oxley compliance reach across nearly all areas of a corporation. In fact, Gartner Research went so far as to call the Act "the most sweeping legislation to affect publicly traded companies since the reforms during the Great Depression." Since the bulk of information in most companies is created, stored, transmitted and maintained electronically, one could logically conclude that IT shoulders a lion's share of the responsibility for Sarbanes-Oxley compliance. Enterprise IT departments are responsible for ensuring that sound practices, including corporate-wide information security policies and enforced implementation of those policies, are in place for employees at all levels. Information security policies should govern:

• Network security
• Access controls
• Authentication
• Encryption
• Logging
• Monitoring and alerting
• Pre-planning coordinated incident response
• Forensics

These components enable information integrity and data retention, while enabling IT audits and business continuity.

In order to comply with Sarbanes-Oxley, companies must be able to show conclusively that:

• They have reviewed quarterly & annual financial reports;
• The information is complete and accurate;
• Effective disclosure controls and procedures are in place and maintained to ensure that material information about the company is made known to them.

Sarbanes-Oxley Section 404

This section regulates enforcement of internal controls. Management must show that it has established an effective internal control structure and procedures for accurate and complete financial reporting. In addition, the company must produce documented evidence of an annual assessment of the internal control structure's effectiveness, validated by a registered public accounting firm. By instituting effective email controls, organizations are not only ensuring compliance with Sarbanes-Oxley Section 404; they are also taking a giant step in the right direction with regards to overall email security.

Effective Email Controls

Email has evolved into a business-critical application unlike any other. Unfortunately, it is also one of the most exposed areas of a technology infrastructure. Enterprises must install a solution that actively enforces policy, stops offending mail both inbound and outbound and halts threats before internal controls are compromised, as opposed to passively noting violations as they occur.

An effective email security solution must address all aspects of controlling access to electronically stored company financial information. This includes access during transport as well as access to static information resident at the company or on a remote site or machine. Given the wide functionality of email, as well as the broad spectrum of threats that face email systems, ensuring appropriate information access control for all of these points requires:

• A capable policy enforcement mechanism to set rules in accordance with each company's systems of internal controls;
• Encryption capabilities to ensure privacy and confidentiality through secure and authenticated transport and delivery of email messages;
• Secure remote access to enable remote access for authorized users while preventing access from unauthorized users;
• Anti-spam and anti-phishing technology to prevent malicious code from entering a machine and to prevent private information from being provided to unauthorized parties

For years, corporations addressed their various email security needs through a mixture of third-party software "solutions" designed to address specific areas of vulnerability. Today, however, this approach is ineffective. New amorphous threats adapt to even the latest security technology, helping hackers and spammers stay a step ahead of most stand-alone protective measures. System administrators remain in a reactionary mode, waiting for the next attack and hoping their mixed bag of security software is up to the test. The new challenges posed to email security demand a new approach that protects enterprises from all types of malicious attacks. Enter CipherTrust's IronMail.
