Cisco Certifications Cisco Systems, Inc. The company is probably best known for its business routing and switching products, which direct data, voice and video traffic across networks around the world. Cisco offers one of the most comprehensive vendor-specific certification programs in the world.
The Cisco Career Certification program begins at the Entry level, then advances to Associate, Professional and Expert levels, and for some certifications caps things off at the Architect level. Figure 1 Cisco Certifications Skill Matrix. Cisco certifications are a de facto standard in networking industry which help you boost your career in the following ways,.
This exam tests a candidate's knowledge and skills related to technologies used to strengthen security of a network perimeter such as Network. The following topics are general guidelines for the content likely to be included on the exam:. Your study will be divided into two distinct parts:. Understanding the technologies as per exam blueprint 2.
Implementing and practicing the technologies on Cisco hardware. IPSpecialist provides full support to enable the candidates for the challenging exam. Certification exams are offered at locations throughout the world. To register for an exam, contact Pearson VUE, the authorized test delivery partner of Cisco, who will administer the exam in a secure, proctored environment.
Decide which exam to take and note down the exam name and number. Refer to the Current Exam List webpage for exam details. Legal name from government issued ID b. Cisco Certification ID i. Company name d. Valid email address. CSCO before continuing with your registration to avoid duplicate records and delays in receiving proper credit for your exams. A valid email is required during exam registration. Cisco requires a valid email to send email reminders when a candidate's certification is about to expire, confirm the mailing address before shipping out the certificate and to inform candidates if their certificate was returned due to an incorrect address.
Pearson VUE is the Cisco authorized test delivery partner. You can register online, by telephone, or by walk in where available. Q: How much an exam costs? Computer-based certification exam or written exam, prices depend on scope and exam length.

After you complete an exam at an authorized testing centre, you will get an immediate online notification in the form of printed examination score report that indicates your pass or fail status, and your exam results section wise. Security is a broad topic, which should be discussed in everything we design, related to computer networking that may be wired or wireless.
Network security has been considered important for quite some time, especially for those of us whose entire careers has been around the field of network security. There has been a surge in public awareness about securing their devices connected to public internet because of events of data stealth and leakage in a past few years. As new vulnerabilities and new methods of attack are being evolved, a least technical user can potentially launch a devastating attack against an unprotected network.
As we strive to empower employees around the world with ubiquitous access to important data, it is increasingly important to take measures for the protection of data and the entities using it. This section will start with mitigation techniques for common layer 2 attacks followed by lab section, which explains the best practices for network device hardening.
Port security is a very nice layer 2 feature of Cisco IOS, which allows network administrators to bind specific number of MAC addresses to a specific port of networking device along with the violation action if number of MAC address increase or a device whose MAC address is not bind, tries to connect to a port.
Just like router stores remote network entries in a routing table, a switch has its own table known as Content Addressable Memory CAM table which is a fancy word for MAC address table. When a switch is powered on, its CAM table has no entry in it. Whenever, a first frame for specific destination hits the switch, it will be broadcasted to all active ports of that specific VLAN.
In case there is no entry present, the intended frame will be sent to all active ports except the source port to that specific VLAN. Just like routing table, CAM table has its own storage limitation depending on hardware series. At this point, switch will start acting as a HUB, which just broadcasts anything hitting its interfaces. This type of attack is referred to as CAM table overflow attack and port security can be used to mitigate such kind of attacks.
After detecting bogus MAC address or maximum number of MAC address allowed on secured port, a port security feature can perform one of the actions as in Table 1.
Alert generation feature of this action makes it preferable over the aforementioned action. Puts the port in err-disable state and everything gets discarded. In order to bind MAC address to specific switch port which must be either in access or static trunk mode the three options listed in Table 2 are available in Cisco IOS.
By default, only 1 MAC address is allowable on switch-port. Manually binds the MAC address on switch-port. Static Preferred in a scenario where number of secure ports are few. This feature comes handy if large number of secure ports require MAC binding. By using sticky feature, the currently learnt MAC addresses will be bind to the Sticky switch-ports and get stored in running-configuration. Network administrator needs to save the running- configuration to startup-configuration so that these MAC gets permanent as switch gets reboot.
Although a nice feature but modern hacking tools can be used to spoof the MAC address and bypass this security check. Similarly, port security does not work with dynamically configured access or trunk ports. Switch port needs to be in a static access. Modern security techniques such as implementation of Storm control feature is used to mitigate situations when huge number of packets flood through the network either legitimate or bogus traffic. Apart from broadcast traffic, storm control feature can be used to limit multicast and even unicast traffic on Layer 2 port.
In Table 3, few reasons behind the situation when switch or router experiences high network traffic are listed:. Table 3-Reasons behind Traffic Storm and their Description. Some protocols may generate tremendous Protocol Implementation amount of broadcast or multicast traffic, which may result in unavailability of network. Another very likely reason for traffic storm is accidental misconfiguration from network Network Configuration Mismatch engineering.
For example, disabling spanning tree may result in some endless loop within switching segment etc. Depending on the IOS version, storm control can be configured based on bandwidth percentage, packets per second PPS or bits per second bps. Just like port security, storm control feature also performs one of the following action in case of violation.
Table 4-Storm Control Response against Violation Action Description Configured as default option, device will drop Syslog Message the traffic exceeding the level defined by storm control feature and will generate Syslog. Storm control feature will put port in err- disable state on violation along with Syslog message generation.
It is actually very easy for someone to bring accidentally or maliciously a DHCP server in a corporate environment. DHCP snooping is all about protecting against it. Let us consider a disgruntled employee say Bob who has some administrative issues in the.
On embedded device, Bob has installed Back Track, which is a Linux distribution commonly used for penetration testing and ethical hacking.
