Audit Reviews! - Call PBM IT at (888) 233-6471Excellent, comprehensive service and support is important to the long-term success of any network solution. Cisco SMB Support Assistant is designed to meet the needs of small and medium-sized businesses. It is an easy-to-use, cost-effective support program that resolves issues typically encountered by SMBs, ensuring the network stays available and secure. Businesses can get timely diagnostic and troubleshooting tips and advance replacement of parts. A key component to the program is the Cisco SMB Support Assistant Portal, an online secure portfolio of tools that allows customers to recover passwords, access support documentation, perform network health checks, download software patches, and open technical support cases when needed. Cisco Integrated Security on the Next-Generation ISR (1) Delivers suite of built-in capabilities, including firewall, intrusion prevention, VPN, and content filtering, (2) Promotes integrating new network security features on existing routers, (3) Provides additional protection without adding hardware and maximizes network security, and (4) Decreases ongoing support and manageability costs by reducing the total number of devices required. Cisco Adaptive Wireless IPS Software (1) Provides automated wireless vulnerability and performance monitoring to deliver visibility and control across the network, (2) Maintains a constant awareness of the RF environment to meet the demands of the largest networks, (3) Automatically monitors for wireless network anomalies and to identify unauthorized access and RF attacks, and (4) Collaborates with Cisco network security products to create a layered approach to wireless security. Network security starts from authenticating the user, commonly with a username and a password. Since this requires just one thing besides the user name, i.e. the password which is something you 'know', this is sometimes termed one factor authentication. With two factor authentication something you 'have' is also used (e.g. a security token or 'dongle', an ATM card, or your mobile phone), or with three factor authentication something you 'are' is also used (e.g. a fingerprint or retinal scan). Once authenticated, a firewall enforces access policies such as what services are allowed to be accessed by the network users] Though effective to prevent unauthorized access, this component may fail to check potentially harmful content such as computer worms or Trojans being transmitted over the network. Anti-virus software or an intrusion prevention system (IPS)[3] help detect and inhibit the action of such malware. An anomaly-based intrusion detection system may also monitor the network and traffic for unexpected (i.e. suspicious) content or behaviour and other anomalies to protect resources, e.g. from denial of service attacks or an employee accessing files at strange times. Individual events occurring on the network may be logged for audit purposes and for later high level analysis. Communication between two hosts using the network could be encrypted to maintain privacy. Honeypots, essentially decoy network-accessible resources, could be deployed in a network as surveillance and early-warning tools. Techniques used by the attackers that attempt to compromise these decoy resources are studied during and after an attack to keep an eye on new exploitation techniques. Such analysis could be used to further tighten security of the actual network being protected by the honeypot. In recent years, security needs have intensified. Data communications and e-commerce are reshaping business practices and introducing new threats to corporate activity. National defense is also vulnerable as national infrastructure systems, for example transport and energy distribution, could be the target of terrorists or, in times of war, enemy nation states. On a less dramatic note, reasons why organisations need to devise effective network security strategies include the following: (1) Security breaches can be very expensive in terms of business disruption and the financial losses that may result, (2) Increasing volumes of sensitive information are transferred across the internet or intranets connected to it, (3) Networks that make use of internet links are becoming more popular because they are cheaper than dedicated leased lines. This, however, involves different users sharing internet links to transport their data, and (4) Directors of business organizations are increasingly required to provide effective information security. For an organization to achieve the level of security that is appropriate and at a cost that is acceptable, it must carry out a detailed risk assessment to determine the nature and extent of existing and potential threats. Countermeasures to the perceived threats must balance the degree of security to be achieved with their acceptability to system users and the value of the data systems to be protected. Integrate security testing into the risk management process. Testing can uncover unknown vulnerabilities and misconfigurations. As a result, testing frequencies may need to be adjusted to meet the prevailing circumstances, for example, as new controls are added to vulnerable systems or other configuration changes are made because of a new threat environment. Security testing reveals crucial information about an organizations security posture and their ability to surmount attack externally or to avoid significant financial or reputational cost from internal malfeasance. In some cases, the results of the testing may indicate that policy and the security architecture should be updated. Hence, this insight into the security posture of an organization is highly relevant to a well-functioning risk management program. Network Security Testing involves activities that provide information about the integrity of an organization network and associated systems through testing and verification of network-related security controls on a regular basis. Security Testing refers to Network Security Testing. The testing activities can include network mapping, vulnerability scanning, password cracking, penentration testing, war dialing, war driving, file integrity checking, and virus scanning. One form of attack on computing systems connected to the Internet is eavesdropping on network connections to obtain login ids and passwords of legitimate users [RFC 1704]. Bellcore's S/KEY(TM) one-time password system was designed to counter this type of attack, called a replay attack [RFC 1760]. Several one-time password implementations compatible with Bellcore's S/KEY (TM) system exist. These implementations are increasingly widely deployed in the Internet to protect against passive attacks. Stop security attacks before they affect business continuity. Cisco ASA 5500 Series Adaptive Security Appliances provide intelligent threat defense and highly secure communications services. These solutions help organizations lower their deployment and operational costs while delivering comprehensive network security for networks of all sizes. he Cisco Works Network Compliance Manager (NCM) is a possible solution for Cisco based network (commercial, not free). NCM tracks compliance with a broad variety of regulatory, IT, corporate governance, and technology best practices. It has a sophisticated search capability. |
