...Employ automated tools to continuously monitor workstations, servers, and mobile devices for active, up-to-date anti-malware protection with anti-virus, anti-spyware, personal firewalls, and host-based IPS functionality. All malware detection events should be sent to enterprise anti-malware administration tools and event log servers. The endpoint security solution should include zero-day protection such as network behavioral heuristics. Employ anti-malware software and signature auto-update features or have administrators manually push updates to all machines on a daily basis. After applying an update, automated systems should verify that each system has received its signature update. Configure laptops, workstations, and servers so that they will not auto-run content from USB tokens (i.e., "thumb drives"), USB hard drives, CDs/DVDs, Firewire devices, external serial advanced technology attachment devices, mounted network shares, or other removable media. If the devices are not required for business use, they should be disabled. Configure systems so that they conduct an automated anti-malware scan of removable media when it is inserted. All e-mail attachments entering the organization's e-mail gateway should be scanned and blocked if they contain malicious code or file types unneeded for the organization's business. This scanning should be done before the e-mail is placed in the user's inbox. This includes e-mail content filtering and web content filtering. Apply anti-virus...

...EIGRP Vs OSPF EIGRP - Is an advanced distance-vector routing protocol, with optimizations to minimize both the unstable route incurred after topology changes, as well as the use of bandwidth and processing power in the router. Routers supporting EIGRP will automatically redistribute route information to IGRP neighbors by converting the 32 bit EIGRP metric to the 24 bit IGRP metric. Most of the routing optimizations are based on the Diffusing Update Algorithm (DUAL) work from SRI, which guarantees loop-free operation and provides a mechanism for fast convergence. IGRP is created by Cisco. OSPF - Open Shortest Path First (OSPF) is a link-state routing protocol for IP networks. It uses a link state routing algorithm and falls into the group of interior routing protocols, operating within a single autonomous system (AS). OSPF is the most widely used interior gateway protocol (IGP) in large enterprise networks. OSPF is a trusted Cisco course-plotting method that creates managing big systems achievable. OSPF represents "Open Least Route 1st. inch this smallest journey would be the one particular with the cheapest. OSPF uses a metric to look for the volume of over head it'd price tag to be able to post info spanning a presented interface. This course-plotting criterion makes use of this specific metric to choose the most efficient journey in between resource and getaway.

...NT2640 Cisco Routers Richard P Walsh 11/24/2015 Cisco routers come in various series and models. Each series and model has different purposes and performance levels for the tasks required of them. For the purpose of this report, I chose 1 model from the 3 main series. The first is the Cisco 1861, then the Cisco 2811, & finally the Cisco 3845 The Cisco 1861 is an Integrated Service Router, that has an integrated, managed Ethernet switch, and has eight 10/100 PoE ports. It is an All-in-One unified communications solution, which integrates voice, data, security, and video into one platform. The Cisco 1861 can be easily expanded by attaching a Cisco recommended Catalyst Portfolio of switches. The Cisco 1861 eliminates the cost of adding multiple servers and provides a lower price solution that is easy to set up and manage. Cisco IOS Software security feature is also an option that can be activated with hardware-based encryption on the motherboard and provides a variety of security features such as a Firewall, IP Security, and an Advanced Encryption Standard, just to name a few. This router is highly recommended for SBMs and small branch enterprises consisting of eight to fifteen employees. Some of the specifications are; DRAM * Cisco IOS Software – 256 MB * Voice Messaging – 512 MB Compact Flash Memory * Cisco IOS Software – 128 MB * Voice Messaging – 1 GB, Compact Flash Onboard Ethernet Ports * 1 10/100 Fast Ethernet * 8 10/100-Mbps LAN ...

...Kelly Keys NT2640 Fri. Night Project Paper 1. Routing tables and how the router will perform a route lookup: a. Routing Table Format- A routing table is used by TCP/IP network routers to calculate the destinations of messages it is responsible for forwarding. The table is a small in-memory database managed by the router's built-in hardware and software. Each IP address identifies a remote router (or other network gateway) that the local router is configured to recognize. For each IP address, the routing table additionally stores a network mask and other data that specifies the destination IP address ranges that remote device will accept. Home network routers utilize a very small routing table because they simply forward all outbound traffic to the Internet Service Provider (ISP) gateway which takes care of all other routing steps. Home router tables typically contain ten or fewer entries. By comparison, the largest routers at the core of the Internet backbone must maintain the full Internet routing table that exceeds 100,000 entries and growing as the Internet expands. b. Routing Lookup Mechanism- c. Classful vs. Classless Routing- Classful Routing, which is sometimes called a classful network. If you are using a classful routing protocol then all of your networks are in different classes and are separated by a router. Remember that the useable IPv4 address ranges are divided into classes. Class A 1-126, Class B 128-191, and Class C 192-223. So when we talk about...

...Lab 7.1 routing analysis 3 Step 2. Again on each PC, ping the IP address of each PC’s respective default gateway. Record whether the ping worked or not in Table 5. Each ping to the PC has worked to the default gateway. Step 3. From each PC, ping the IP address of the other three PCs. Record the results of each ping in Table 6 with a check mark for a successful ping and an X for a failed ping. None of the PC’s pinged to the other pc’s. Step 5. From each router’s user mode command prompt, ping the IP addresses of each other router. Make notes about which IP addresses can be pinged from each router. Each router has pinged the other routers IP’s on the common LAN subnet but none of the pings worked from a router to each others routers. Step 6. Use the show ip route and show ip routes ospf commands to examine each router’s routing tables. Do any of the four routers know any routes other than connected routes? Do any of the routers know any OSPF-learned routes? None of the routers have any OSPF routes. This is one of the reasons why the PC’s cant ping the other routers. Step 7. From each router, use the show ip ospf neighbor command to discover with which other routers each router has formed a neighbor relationship. List the router pairs that have formed any kind of neighbor relationship on the lines below. None of the routers have OSPf neighbor relationships with the other routers. Step 8.
