IT Consulting with Computer Support Services - Los Angeles - Firewall
Converged networks result from designing a common enterprise, networking infrastructure to accommodate both data and voice communication (Figure 2). The basic network infrastructure is designed to allow IP telephony communication to occur within an enterprise with quality of service guarantees. The network architecture may support single site, multi-site, branch office, remote office, and mobile workers to deliver voice and data content.
Establishing and securing enterprise networks requires comprehensive policies and processes to be in place. Technology alone cannot make an enterprise secure. Establishing a security policy is the initial step that an enterprise must take toward defining and deploying its own security plan. It is outside the scope of this document to describe the details in a security policy and the process for defining a security plan. There are many publications on the topic. The Site Security Handbook, RFC 2196, is one such document that may be referenced for additional information."
We also support Firewall most major operating systems including HP 9000 UNIX, Sun Solaris and Microsoft. We specialize in the integration of multi-vendor platforms.
An opportunity offered by converged networking is to provide a seamless security infrastructure that protects against attacks on network devices as well as on applications. In the traditional environment, voice networks, data networks, and voice and data applications are often implemented using unique security mechanisms to detect and respond to attacks. Firewalls and intrusion detection systems (IDS) can prevent and detect attacks on the data network. Application specific mechanisms, coupled with management systems, are designed to detect voice network and data application attacks. In the converged network, a seamless yet comprehensive security infrastructure is possible.
The converged security infrastructure provides device protection that recognizes and responds to attacks, as well as application protection to control access and to recognize and respond to detected abuse. Delegated administration of the security infrastructure permits segmentation of work tasks to the responsible job classification. This segmentation is typically dictated by the security policy to flexibly manage security operations.
Enabling Firewall improvements and flexibility to enterprises' business continuity planning and disaster recovery is an important benefit of converged networks. For example, business continuity planning, the proactive process that identifies potential threats to the operation of key business functions and forms plans for continuing those functions when a disruption develops, is afforded new alternatives for distributing critical business capabilities through the convergence of voice and data onto a common infrastructure. Disaster recovery, the activity of returning a business function to normal or degraded operation following a foreseen or an unforeseen event, find that applications and information are easily partitioned, transferred, and remotely accessible due to the flexibility of IP networks and wireless networks.
Although networking equipment and application capabilities may support business continuity plans and disaster recovery, they are only part of a larger set of policies, plans, and infrastructure. Converged networking features such as automatic failover to remote locations and calling precedence and preemption can play a part in executing business continuity and disaster recovery plans. However, to leverage such features enterprises must have policies, procedures, and plans in place to deal with disaster and disruption. Firewall new Business Realities Web site offers insight into achieving business continuity through communications technology."'
2.1.1 Threats in Converged Networks
Deploying voice applications on the converged infrastructure exposes the applications to new threats of disclosure, integrity, and denial of service. Each threat and threat category highlight the potential for the loss of significant tangible and intangible business value.
Disclosure
Threats of disclosure include eavesdropping. Eavesdropping involves listening to conversations that would otherwise be private. In the data world eavesdropping involves sniffing network packets for data that can be interpreted in real-time or saved for later analysis or playback. In the converged space, the new eavesdropping threat involves sniffing voice conversations. The probability of being vulnerable to eavesdropping increases as voice applications move to converged networks because shared IP networks are directly accessible with wider user access and thus are easier to sniff for traffic than are traditional voice networks.
Privacy of stored data is also of concern. Stored data represents intellectual property, configuration information, transaction history, log files, and other information that is proprietary to enterprises. In total, loss of proprietary information makes up a significant portion of the total dollar loss due to security breaches; $170M as reported in the 2002 CSI/FBI Computer Crime and Security Survey.'° Aside from the direct loss of proprietary information, stored communication records can be used to construct a traffic analysis. A traffic analysis reveals the proprietary behaviors of an enterprise and potentially allows the patterns of movement of specific employees to be tracked and targeted.
Historically, access to private data is protected differently in traditional networks than converged networks. In traditional networks, voice devices are not connected to the IP network. Physical security, i.e. maintaining equipment within locked rooms (communication closets), is a significant part of the traditional network's security strategy. Data contained within a device is difficult to attack when systems are less accessible. Though the data still needs to be protected, a certain amount of protection is gained through physical security means. In converged networks, all devices are connected to the IP network. As a result, communication devices are more readily open to attacks to gain unauthorized access. Stored messages, call history records, configuration files, interactive voice response scripts, and log files are all potentially vulnerable.
Encryption can prevent disclosure threats. Encrypting media streams is one technique to prevent disclosure of voice conversations. Encrypting stored files is a technique to prevent loss of sensitive data. Access
