OTP Security - Call (888) 233-6471 for One-Time Password HelpWith attacks on the rise, businesses and customers need assurance they are protected from the disruption and cost-of-service outages or corrupted data. The proven Cisco Self-Defending Network is a multifaceted approach that protects businesses from the devastating effects of worms, viruses, cyber-terrorists, and other attacks. Computer viruses, worms, and spyware typically enter businesses via e-mail or IM applications, Web downloads, or file transfers, although sophisticated attacks can enter via mobile wireless services or operating system services. Industry-leading Cisco Intrusion Prevention Systems (IPSs) scan and inspect all incoming traffic in real time, looking for known irregularities that may signal an attack. If an anomaly is detected, a Cisco security appliance rates the severity of the risk and communicates to other security-aware network components. This way, they can stop the threat at the source immediately and prevent it from spreading through the network. Worms, viruses, and spyware aren’t the only way businesses can be attacked. Cisco security appliances use the same traffic and application inspection capabilities to detect and repel DoS attacks, or other attacks so new they don’t have a name yet. Integrated security throughout the business stops known and unknown attacks in real time, and communication between network components allows them to adapt to changing security conditions. These layers of security allow small and medium-sized businesses to continue to respond to customers and stay open for business even while under attack Cisco IronPort Web Security Appliances (1) Integrate industry-leading web-usage controls, reputation filtering, malware filtering, and data security, (2) Take advantage of Cisco Security Intelligence Operations (SIO) and global threat correlation technology to help optimize threat detection and mitigation, (3) Combine multiple layers of web security technology to combat complex and sophisticated web-based threats, and (4) Support built-in management capabilities to simplify administration and provide visibility into threat-related activity. With netForensics security information and event management (SIEM) and log management solutions, Cisco customers can depend on accurate, comprehensive security information using a single, unified view across all network systems, security devices and applications. The nFX One family of software and appliance products collect, centralize and store volumes of diverse data, and deliver understandable, actionable security intelligence. Users can now easily see all the information that is important and not lose visibility due to overwhelming volumes of diverse event data. This prioritized insight dramatically improves your ability to identify and rapidly respond to the true threats, and stop them in their tracks before real damage occurs. These advanced solutions for real-time monitoring, event correlation, threat management and reporting are helping organizations of all types and sizes meet today’s most demanding data protection and compliance challenges. Now, you can protect your critical data, manage log overload, and ensure audit readiness regardless of your budget, size, and performance requirements. DoS (Denial-of-Service) attacks are probably the nastiest, and most difficult to address. These are the nastiest, because they're very easy to launch, difficult (sometimes impossible) to track, and it isn't easy to refuse the requests of the attacker, without also refusing legitimate requests for service. The premise of a DoS attack is simple: send more requests to the machine than it can handle. There are toolkits available in the underground community that make this a simple matter of running a program and telling it which host to blast with requests. The attacker's program simply makes a connection on some service port, perhaps forging the packet's header information that says where the packet came from, and then dropping the connection. If the host is able to answer 20 requests per second, and the attacker is sending 50 per second, obviously the host will be unable to service all of the attacker's requests, much less any legitimate requests (hits on the web site running there, for example). Such attacks were fairly common in late 1996 and early 1997, but are now becoming less popular. Some things that can be done to reduce the risk of being stung by a denial of service attack include (1) Not running your visible-to-the-world servers at a level too close to capacity, and (2) Using packet filtering to prevent obviously forged packets from entering into your network address space. Obviously forged packets would include those that claim to come from your own hosts, addresses reserved for private networks as defined in RFC 1918 [4], and the loopback network (127.0.0.0), and (3) Keeping up-to-date on security-related patches for your hosts' operating systems. Masquerade attacks, as the name suggests, relate to an entity (usually a computer or a person) taking on a false identity in order to acquire or modify information, and in effect achieve an unwarranted privilege status. Masquerade attacks can also incorporate other categories. Security testing is important for understanding, calibrating, and documenting the operational security posture of an organization. Aside from development of these systems, the operational and security demands must be met in a fast changing threat and vulnerability environment. Attempting to learn and repair the state of your security during a major attack is very expensive in cost and reputation, and is largely ineffective. Evaluation of system security can and should be conducted at different stages of system development. Security evaluation activities include, but are not limited to, risk assessment, certification and accreditation (C&A), system audits, and security testing at appropriate periods during a systems life cycle. These activities are geared toward ensuring that the system is being developed and operated in accordance with an organization’s security policy. This section discusses how network security testing, as a security evaluation activity, fits into the system development life cycle. The standard one-time password dictionary from RFC 1760 helps maintain backwards compatibility with the various deployed systems, however, support for hexadecimal format passwords will also be mandatory to implement. The standard might specify pass phrase quality checks for the secret pass phrase. The standard will be specified so as to eliminate any possible conflict with the Bellcore trademark on the term S/Key. 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. The configuration files tend to be hundreds of pages long, and full of confidential information such as passwords, and addresses. The solution here is to ask network administrators to provide output of a script or single command after removing confidential information. This way, the auditor doesn't need to read through a long printout, and can focus only on important information. |
