Identity Management

Cisco  Secure Access Control System (ACS) controls network access policy and identity strategy in a company . Cisco Secure ACS is the world’s most robust and entrusted software security access and policy platform.

Cisco Secure ACS 5.2 provides traditional services like  RADIUS and TACACS+. It supports the complex policies needed to meet today's new demands for access control management and compliance. In Effect the if then else graphical user interface ensures that the  Cisco Secure ACS provides centralized management of access policies for device administration and wired and wireless 802.1x network access implementations.

In Today’s modern networks there is an ever increasing demand on security administrators to provide centralized controlled access across the lan and wan and minimize security breaches and satisfy security compliancy. Network security officers and administrators need solutions like the Cisco ACS security appliances that support flexible authentication and authorization and accounting policies that are tied to a user’s identity as well as the network access type, time of day, and the security of the machine used to access the network.

Networks are now driven by Regulatory compliance and governance that  require an effective network audit, monitoring and a set base of compliance reporting to satisfy these regulatory requirements.

Cisco Secure ACS provides an organization with Cisco ACS Authentication, Cisco ACS Authorization and Cisco ACS Accounting on the network so that network assets are protected automatically from unauthorized access in and out of the enterprise. Cisco Secure ACS is a robust and scalable solution to satisfy security system centralization device administration, authentication, and user access policy that reduces the management and support.

Typical deployment scenarios

 

Authentication Authorization and Accounting (AAA)access and Terminal Access Controller Access-Control System  (TACACS+)
 
All Network Switches Firewall's and Routers supporting the AAA and TACACS+ protocol are eligible to work with the Cisco ACS solution engine.

Remote Access Using Cisco VPN ipsec or SSL or VPN over LAN
Cisco VPN's uses advanced encryption and tunneling to permit organizations and users to establish secure, end-to-end, private network connections over third-party networks, such as the Internet or extra net. Typically, the policy features used with VPN access are downloadable Access lists  and Network address restrictions .Dual factor authentication may also be employed using RSA tokens integrated with Cisco ACS system

Wireless Network Access Services
The wireless AP provides a bridged connection for mobile clients into the LAN. The 802.1X standard controls access to the AP. Authentication is necessary because of ease of access to the AP. Encryption is also a necessity because of the ease of eavesdropping on communications. As such, security plays an even bigger role than in the dial up or VPN access. To protect user credentials in this exposed environment, use of EAP is strongly encouraged. As discussed earlier about EAP types, each EAP type has its restrictions on password type, available external database and security provided.

As with other access methods, wireless access policies may also incorporate NAR's, session and idle timeouts, and max-sessions. Also, if the wireless access supports it, you can also provide VLAN information to control network access. Because EAP uses RADIUS, you can also leverage NAPs to provide additional granularity for returned RADIUS attributes, VLAN's, and so on.

LAN Network
The need for secure network access has never been greater. In today's diverse workplaces, consultants,
contractors, and even guests require access to network resources over the same LAN connections as regular
employees, who may themselves bring unmanaged devices into the workplace. As data networks become
increasingly indispensable in day-to-day business operations, the possibility that unauthorized people or devices will
gain access to controlled or confidential information also increases.
The best and most secure solution to vulnerability at the access edge is to use the intelligence of the network. Cisco
IOS Software enables standards-based network access control at the access layer by using the IEEE 802.1X
protocol to secure the physical ports where end users connect. IEEE 802.1X is an IEEE standard for media-level
(Layer 2) access control, offering the capability to permit or deny network connectivity based on the identity of the
end user or device
