Cisco ASA/Pix Operation
A 4 day instructor-led practical course designed to familiarise delegates with the Cisco ASA Firewall CLI and ASDM. The course details the key commands used to configure and secure networks using the ASA Firewall with v8 of the operating system and version 6 of the ASDM.
Delegates will configure the ASA using the console port, TFTP server, telnet and SSH using local and RADIUS authentication. The device will be configured to utilise Syslog and SNMP.
ASA Firewalls will also be configured to use Access-Lists, Network Address Translation and VPN's utilising IPSec protocols. The course will cover the theory of Public/Private Keys, shared secret keys and their use in forming Site to site VPN's between ASA Firewalls using IKE and IPSec. Students will configure the units to create site to site VPN's, remote access VPN's using the Cisco Secure VPN Client and Web VPN's. The course will cover the theory of failover and delegates will configure Active/Standby failover on the ASA.
Privileged commands and protocol analyser traces will be used, where necessary, to debug protocols and ensure proper operation of the ASA Firewall. Students will also perform password recovery operations.
This course will involve interfacing the ASA with other network equipment, such as routers and switches, as would be expected in a network environment.

Cisco CCNA Syllabus in 5 Days
A 5 day practical networking course designed to familiarise students with Cisco IOS (version 12). The course details the key commands used to configure and secure Cisco routers and switches, and covers the CCNA syllabus - including wired and wireless LAN access.
Students will inter-connect networks by implementing static routes, distance-vector and link-state based dynamic routing protocols.
The devices will be configured to route traffic across LAN/VLAN//WAN boundaries, by encapsulating datagrams across serial data links using various WAN protocols, such as HDLC, Frame Relay, ISDN and PPP (with CHAP authentication). VLAN encapsulation/tagging will be via IEEE802.1Q/P.
Standard and Extended Access Control Lists will be configured and applied to router interfaces to filter traffic based on IP address and/or traffic type.
Students will configure static and dynamic NAT to route between private and public networks and cover the theory of Virtual Private Networks (VPN's)
Students will copy router configurations and IOS images to/from a TFTP Server. Privileged commands will be used to debug TCP/IP protocols to ensure proper operation of the routers. Students will also perform password recovery operations.
The course is primarily aimed at IP v4 but does give an overview of IP v6 addressing and covers migration from an IP v4 to an IP v6 network. Other protocols and technologies (VPN's / Wireless) may be demonstrated if time permits.
Course can be customised to precise requirements of customer.

SIP protocol in VoIP
The course consists of two complementary parts – a theoretical and a practical one. The first is a one day introduction covering motivation, philosophy, fundamentals and rules of operation of the SIP protocol and ways it is used to implement telecom services with focus on IP telephony and VoIP. The second two-day part enables participants to learn practical aspects of service operation within a framework of hand-on laboratory exercises giving detailed insight into configuration of components of SIP telephony architecture, SIP signalling at both message sequence chart and internal message structure levels, and assists in understanding of typical problems and troubleshooting including security and telecom fraud aspects. The trainers will share their experience in launching, operation and management of SIP telephony covering also virtualization and cloud based solutions. Practical part is presented using both SIP hardphones and softphones and IP telephony servers (Asterisk and Freeswitch). Participants can take advantage of the fact trainers have got rich technical and business experience in IP telephony and submit their own problems and questions. They will be included in the agenda at wrap-up as a supplement to the training to meet current urgent needs of clients.
