Cisco Firewalls - Call PBM IT at (888) 233-6471Todays globally competitive business environment has small and medium-sized businesses focused on expanding their business and improving customer satisfaction while simultaneously controlling costs. Fortunately, the Internet and networked applications have leveled the playing field. Small and medium-sized businesses use their networks to extend their market reach and communicate with their customers and partners quickly and cost-effectively. But swift and agile e-business is a double-edged sword, access can also open up businesses to costly security breaches. It is more important than ever to have a reliable, secure, and available network. ScanSafe Web Security (1) Analyzes every web request to determine whether content is malicious, inappropriate, or acceptable, (2) Offers granular control over all web content, including SSL-encrypted communications, (3) Extends real-time protection and policy enforcement to employees wherever or however the Internet is accessed, and (4) Helps ensure highly secure email communications by blocking unwanted and malicious emails, while protecting confidential data. netForensics solutions provide all the essential elements of an effective SIEM and log management strategy, including (1) Ongoing data collection from a broad array of network and security devices, (2) The capability to aggregate, correlate and store diverse security log data, (3) Complete visibility into security-related activities, so you always know your security and compliance posture, (4) Real-time identification of threats and patterns of suspicious activity, (5) Rapid, best-practice response guidance for security incidents, (6) Tools and reports to effectively meet your compliance requirements, and (7) Scalable architectures that ensure a low cost of ownership as you grow. Network security involves all activities that organizations, enterprises, and institutions undertake to protect the value and ongoing usability of assets and the integrity and continuity of operations. An effective network security strategy requires identifying threats and then choosing the most effective set of tools to combat them. Important terms used for describing how data is stored, processed or transmitted to other locations: (1) Confidentiality, in terms of selecting who or what is allowed access to data and systems. This is achieved through encryption and access control systems. Even knowledge of the existence of data, rather than the information that it contains, may be of significant value to an eavesdropper, (2) The integrity of data, where modification is allowed only by authorized persons or organizations. The modifications could include any changes such as adding to, selectively deleting from, or even changing the status of a set of data, (3) The freshness of data contained in messages. An attacker could capture part or all of a message and re-use it at a later date, passing it off as a new message. Some method of incorporating a freshness indicator (e.g. a time stamp) into messages minimizes the risk of this happening, (4) The authentication of the source of information, often in terms of the identity of a person as well as the physical address of an access point to the network such as a workstation, and (5) The availability of network services, including security procedures, to authorized people when they are needed. 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. Cisco ASA 5500 Series Adaptive Security Appliances also provide (1) Adaptable architecture for rapid and customized security services deployment, (2) Advanced intrusion prevention services that defend against a broad range of threats, and (3) Highly secure remote access and unified communications to enhance mobility, collaboration, and productivity. 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. |
