Security

What are you trying to protect?

The security policy usually attempts to protect information, whether the information is in the form of data (files) or conversations (digitized voice packets). Customers should assess the value of those assets that require protection, and compare the true costs of security to the value of those assets.

What are you protecting it from?

Most often, criminals, who are also called “hackers,” pose a significant threat to secure information. However, do not forget to look internally. A significant number of attacks come from within an enterprise. Your security policy should include rules about behavior, the consequences of bad behavior, a path of escalation, and a person to contact with regard to security issues.

How likely is a threat against these assets?

Security is always a trade-off. The more security, the more inconvenience and the more cost. To avoid the necessary inconvenience, some users are likely to subvert the security policy. For example, if you make passwords so complex so that the passwords are difficult to remember, people will write the passwords down. Users prefer easy access without security. Having to log on is inconvenient. However, everyone must endure some level of inconvenience if the system is going to be secure against attacks. The security policy must define this level of inconvenience to ensure that the security polity is not circumvented. In addition, management must support the policy, and establish clear rules for its enforcement, including the consequences for violating it. A security policy that does not establish consequences for violations quickly becomes irrelevant.

Recommendations for your security policy

Avaya recommends that you continuously review your security policy, and keep up with new threats and to make improvements each time a weakness is found. To effectively support your security policy, your company must allocate long-term resources to the development, implementation, and reassessment of the policy.
