Easy Internet access, increasing numbers of users and the proliferation of wireless networks have made information security (IS) a major concern for businesses and government agencies. With access to information easier than ever, businesses must bolster their networks to ensure there are no holes in their infrastructure through which unauthorized visitors can gain access. Additionally, businesses must protect their networks from internal abuse by authorized users within their organizations. With IS, businesses should employ a layered approach that includes the integration of anti-virus, SPAM, content filtering, firewalls and intrusion-detection products. Working together, these solutions guard your network and reinforce your organization’s security policies. After they are installed, integrated security systems require updating and monitoring. Outdated security products are an invitation for abuse. Furthermore, an un-monitored security suite may detect, but not prevent abuse.
