How to Troubleshoot RAM Memory

When you have memory problems, you know you are limited in your troubleshooting and hopefully you will be able to resolve the problem quickly. It’s a great idea to first verify the problem exist.

Shutdown and reboot your computer to see if the problem re-appears. Sometimes rebooting the PC will correct the problem and you'll be on your way.

How to Configure Extended Access List On Router

Configure Extended Access Lists

An extended ACL gives you much more power than just a standard ACL. Extended IP ACLs check both the source and destination packet addresses. They can also check for specific protocols, port numbers, and other parameters, which allow administrators more flexibility and control.

access-list access-list-number {permit | deny}
protocol source source-wildcard [operator port]
destination destination-wildcard [operator port]
[established] [log]

Command Parameters	Descriptions
access-list	Main command
access-list-number	Identifies the list using a number in the ranges of 100.199 or 2000. 2699.
permit | deny	Indicates whether this entry allows or blocks the specified address.
protocol	IP, TCP, UDP, ICMP, GRE, or IGRP.
source and destination	Identifies source and destination IP addresses.
source-wildcard and destination-wildcard	The operator can be lt (less than), gt (greater than), eq (equal to), or neq (not equal to). The port number referenced can be either the source port or the destination port, depending on where in the ACL the port number is configured. As an alternative to the port number, well-known application names can be used, such as Telnet, FTP, and SMTP.
established	For inbound TCP only. Allows TCP traffic to pass if the packet is a response to an outbound-initiated session. This type of traffic has the acknowledgement (ACK) bits set. (See the Extended ACL with the Established Parameter example.)
log	Sends a logging message to the console.

How to Configure Standard Access List On Router

Standard Access Lists

Because a standard access list filters only traffic based on source traffic, all you need is the IP address of the host or subnet you want to permit or deny. ACLs are created in global configuration mode and then applied on an interface. The syntax for creating a standard ACL is

access-list {1-99 | 1300-1999} {permit | deny} source-address
 [wildcard mask]

In this article we will configure standard access list. If you want read the feature and characteristic of access list reads this previous article.

Access control list

In this article we will use a RIP running topology. Which we created in RIP routing practical.

Access Control List Standard Extended

Access Control List

ACLs are basically a set of commands, grouped together by a number or name that is used to filter traffic entering or leaving an interface.
When activating an ACL on an interface, you must specify in which direction the traffic should be filtered:

• Inbound (as the traffic comes into an interface)
• Outbound (before the traffic exits an interface)

Inbound ACLs:
Incoming packets are processed before they are routed to an outbound interface. An inbound ACL is efficient because it saves the overhead of routing lookups if the packet will be discarded after it is denied by the filtering tests. If the packet is permitted by the tests, it is processed for routing.

Outbound ACLs:
Incoming packets are routed to the outbound interface and then processed through the outbound ACL.

Network Security Mitigating Common Threats

Improper and incomplete network device installation is an often-overlooked security threat that, if left unaddressed, can have terrible results. Software-based security measures alone cannot prevent intended or even accidental network damage caused by poor installation. Now we will describe how to mitigate common security threats to Server Routers and Switches.

Physical Installations

Physical installations involve four types of threats:
hardware, electrical, environmental, and maintenance.

Hardware threats

Hardware threats involve threats of physical damage to the router or switch hardware. Mission-critical Cisco network equipment should be located in wiring closets or in computer or telecommunications rooms that meet these minimum requirements:

Network Security Types of Attack Reconnaissance Attack

Reconnaissance Attacks

A reconnaissance attack occurs when an adversary tries to learn information about your network.

Reconnaissance is the unauthorized discovery and mapping of systems, services, or vulnerabilities.

Reconnaissance is also known as information gathering and, in most cases, precedes an actual access or DoS attack. First, the malicious intruder typically conducts a ping sweep of the target network to determine which IP addresses are alive. Then the intruder determines which services or ports are active on the live IP addresses. From this information, the intruder queries the ports to determine the type and version of the application and operating system running on the target host.

Network Security

A security policy defines what people can and can't do with network components and resources.

Need for Network Security

In the past, hackers were highly skilled programmers who understood the details of computer communications and how to exploit vulnerabilities. Today almost anyone can become a hacker by downloading tools from the Internet. These complicated attack tools and generally open networks have generated an increased need for network security and dynamic security policies.

The easiest way to protect a network from an outside attack is to close it off completely from the outside world. A closed network provides connectivity only to trusted known parties and sites; a closed network does not allow a connection to public networks.
Because they have no Internet connectivity, networks designed in this way can be considered safe from Internet attacks. However, internal threats still exist.
There is a estimates that 60 to 80 percent of network misuse comes from inside the enterprise where the misuse has taken place.

What Is a Network?

The first assignment in understanding how to build a computer network is defining what a network is and understanding how it is used to help a business meet its objectives.

Network is a combination of computer hardware, cabling, network devices, and computer software used together to allow computers to communicate with each other.

Or

A network is basically all of the components (hardware and software) involved in connecting computers across small and large distances. Networks are used to provide easy access to information, thus increasing productivity for users.

Network hardware is mainly made by two basic components: the entities that want to share the information or resources, such as servers and workstations, and the medium that enables the entities to communicate, which is a cable or a wireless medium

Entering Debug:

Debug has been included in every version of MS-DOS as well as Windows. When running any of the debug routines it is recommended that if you have Windows that you exit or shut down to get into a real DOS prompt (unless you're running Windows ME, Windows 2000, Windows XP, or later versions).

Once at the MS- DOS prompt, run through the below example, this example is perfectly fine to run on any PC Computer running MS-DOS / Windows and will not harm anything. Type debug and press enter. This should get you to a - (small dash). This is the debug prompt. At the - type d40:00 and press enter; this will return several lines of information. After the feedback you will be back to the debug prompt. To exit out of debug type q and press enter. This will return you back to the MS-DOS prompt.

In some of the below debug routines you will notice that a "g" is typed, then "q". G tells the computer that the code type is not self executing and must be run at this point. If completed, the program will return Program Terminated Normally which indicates you can now quit from the debug program.
