How to use Network Monitoring Software

What Network Monitoring is?

Network monitoring is the process of recording all computer and Internet activity that seems to occur on the PC’s in your network. By this you can almost record EVERYTHING anyone does on your network. By different features of monitoring user can even observe activities of a single user across multiple PC’s. This is great if users have way in to multiple computes all through the network. You can view all the information from that user for all the computers they were accessing and using. By Network-Monitoring Software you can keep an eye on your network. In this you can record emails, keystrokes, websites, usernames, passwords, screenshots, chat messages, instant messages, applications ran, and further. All of this comes with date, time, and the duration of time it was accessed.

Benefits of Network Monitoring

2. Increase employee productivity and boost PROFITS!

By monitoring your employees you will considerably increase the productivity of your employees. Amplified productivity equals increased profits for your company. It is expected that approximately 75 minutes every day is used for non-business related activity on company computers for EACH employee. This translated into an annual loss of $6,250 per employee in income assuming your employees are paid the U.S. average of $20 per hour. See in your mind’s eye if your employee’s salary is higher!

3. Eliminate leaking of private material
The most greatest assets in your company is the data enclosed within it. Protect your private data from leaking to third-parties through monitoring your computers action across the network.

4. Recover important communications that have been gone

By monitoring your networks key data and communication it is always logged. Imagine if an employee’s work was lost due to a power outage, a problem with the PC, or plain employee error – now it will always be logged and can always be retrieved safely and in its entirety.

5. Meet or go beyond federal, industry, or agency compliance requirements for keeping records of transactions and communications

6. By monitoring your PC’s you are meeting the industry requirements for storing records and logs of transactions and communications all with the additional benefits listed above. Why wouldn’t you monitor these things?

How a Network Monitoring software being used?

Check out a few situations in which a network monitoring software can be use to watch the network.

1- Business Monitoring

Network Monitoring software can be deployed over a business network in seconds and permit for easy centralized log viewing via one central networked PC. All the network administrator has to do is point and click different users to analyze their activities! No physical presence is required to monitor employees! Now network administrators can monitor large networks from one convenient, secure location! Network monitoring software is a scalable answer – so any network, from a small workgroup, to a large corporate structure, can be monitored by Network monitoring software.

2. Institutional Monitoring

Network Monitoring Software can be used in schools and institutions to monitor the utilization of their public lab workstations. All workstations can be monitored from a central location to ensure they are being used correctly and not being tainted by other users that are coming and going! Multiple rooms and networks can be monitored by one user as of any location for convenient real-time monitoring.

3. Centralized Administration

Network monitoring software can be used to control PC’s over a network from a central site. Administrators can shutdown, logoff, reboot, freeze, or send a message to the maximum users, or all users, on a network. Network monitoring software can additionaly be used to view each user remotely, in real-time.

4. Prevent Security Breaches

Network monitoring software grants administrators to carefully monitor their user’s activities – ensuring they do not open any security holes in their network, or reveal any sensitive information to third parties. In the case that information has been revealed, the administrator can easily view network monitoring software’s stored activity logs for incriminating data for nabbing the responsible party – and closing the source of the information leak.

Network Ping

Ping is the name of a standard software tool which is used to test network connections. It can be used to verify if a remote device “like Web or game server” has reached across the network and, if it is so, the connection latency. Ping tools are the part of Windows, Mac OS X and Linux and some routers as well as game consoles. They send request messages to the specific network address at periodic intervals and calculate the time it takes for a response message to arrive.

Ping is one of those commands that gains lots of attention because it is encountered often. It also get a lot of unwanted attention when less then savvy network administrators attempt to run it from automated scripts or while regular working hours. Ping can generate a major strain on a network, which is why it is best left to it support and for off-hour usage.

Tips to Use Ping for Testing Network Connection:-

1. Create ping a feature that you can hear. If you need a notification, you would also set it to make a noise whenever you received the response. You can do this with ‘-a’.
2. Usa ‘-A’ to sync the rate at which data is sent and received. This option is available to balance the rate in order packets are broadcast and received so that even an average user can also use these features.
3. ‘-b’ is used for broadcast address.
4. ‘-c’ used to stop ping when you are done sending information.
5. ‘-i’ used to instruct ping for how long it has to wait between sending packets. You would specify whatever interval you want, and the default can be set to 1 second between packets.
6. ‘-f’ used to send packets at very fast rates, as high as 100 per second. Normally, only administrative users are able to get benefit of this feature. Due to the strain it places on a network, It is the one of those features that is best left for after hours work through a privileged administrator.
7. ‘-I’ used to name the IP address source.
8. Send a bulky number of packets first before having the system scale back to the normal manner by using the preload function ‘-l’. It is too heavy, but it can be get things off to a quick start.
9. ‘-V’ used to make a print version of the ping report. After printing it, ‘-V’ would exit the program.
10. Make the system to exit ping after a preset number of seconds with the help of ‘-w’. You would want to enter the number of seconds under n.
11. Command the system to time out after a some amount of time when it is waiting for a response with ‘-W’. This is generally specified in seconds n.
12. Organize the 5th edition of the manual for Linux command online from O’Reilly.

Network Security Control

The incidents of security attacks are increasing and frequent accounts of serious security incidents are published by the news media. So, you might have come to a conclusion that network security is hopeless. But, luckily that is not the case since security issues can be addressed by different methods like overlapping controls for defense, reference monitors for access control and encryption for integrity and confidentiality. The most prominent network security control measures include encrypted e-mail, intrusion detection systems and firewalls.

Firewall

A firewall is a part of a computer system or network that is designed to block unauthorized access while permitting authorized communications. It is a device or set of devices that is configured to permit or deny network transmissions based upon a set of rules and other criteria.

Firewalls can be implemented in either hardware or software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the intranet pass through the firewall, which inspects each message and blocks those that do not meet the specified security criteria.

There are several types of firewall techniques:

1. Packet filter: Packet filtering inspects each packet passing through the network and accepts or rejects it based on user-defined rules. Although difficult to configure, it is fairly effective and mostly transparent to its users. It is susceptible to IP spoofing.
2. Application gateway: Applies security mechanisms to specific applications, such as FTP and Telnet servers. This is very effective, but can impose a performance degradation.
3. Circuit-level gateway: Applies security mechanisms when a TCP or UDP connection is established. Once the connection has been made, packets can flow between the hosts without further checking.
4. Proxy server: Intercepts all messages entering and leaving the network. The proxy server effectively hides the true network addresses.

Intrusion Detection System

An intrusion detection system (IDS) inspects all inbound and outbound network activity and identifies suspicious patterns that may indicate a network or system attack from someone attempting to break into or compromise a system.

There are several ways to categorize an IDS:

• misuse detection vs. anomaly detection: in misuse detection, the IDS analyzes the information it gathers and compares it to large databases of attack signatures. Essentially, the IDS looks for a specific attack that has already been documented. Like a virus detection system, misuse detection software is only as good as the database of attack signatures that it uses to compare packets against. In anomaly detection, the system administrator defines the baseline, or normal, state of the network??s traffic load, breakdown, protocol, and typical packet size. The anomaly detector monitors network segments to compare their state to the normal baseline and look for anomalies.
• network-based vs. host-based systems: in a network-based system, or NIDS, the individual packets flowing through a network are analyzed. The NIDS can detect malicious packets that are designed to be overlooked by a firewall??s simplistic filtering rules. In a host-based system, the IDS examines at the activity on each individual computer or host.
• passive system vs. reactive system: in a passive system, the IDS detects a potential security breach, logs the information and signals an alert. In a reactive system, the IDS responds to the suspicious activity by logging off a user or by reprogramming the firewall to block network traffic from the suspected malicious source.

Though they both relate to network security, an IDS differs from a firewall in that a firewall looks out for intrusions in order to stop them from happening. The firewall limits the access between networks in order to prevent intrusion and does not signal an attack from inside the network. An IDS evaluates a suspected intrusion once it has taken place and signals an alarm. An IDS also watches for attacks that originate from within a system.

Encrypted e-mail

Email encryption protects private, sensitive and valuable information communicated via email. Email encryption can be deployed using email encrypting software, secure email servers or secure webmail centers. E-mail encryption can rely on public-key cryptography, in which users can each publish a public key that others can use to encrypt messages to them; while keeping secret a private key they can use to decrypt such messages or to digitally encrypt and sign messages they send.

Comparison of security products for network

A computer network is a joined system of computers and peripherals that may permit them to work in concert, share resources, be controlled and customized centrally, as well as allowing them to be protected or limited as a group. Security software is, generally speaking, any software that helps preserve a system or network from risk or threat or to keep the data itself secure. Computer network security software, then, is software that aims to defend a network and its data in a range of ways and from a variety of threats.

One may frequently think of computer network security software as being separate products or suites of products devoted only to security. But, this kind of opinion would ignore a very important type of security software. The missing component would be the security patches issue by manufacturers of operating systems. They’re aimed and security and they’re software, so even although they are updates to software that is mean to run a computer, they still calculate.

The products that are more expected to come to mind as computer network security, software are those that start with “anti.” These consist of anti-virus software, anti-malware — malware is short for “malicious software,” and anti-spyware. The three names are used somewhat differently by various manufacturers, but generally, the software is designed to catch and disable or prevent the infringement of viruses, worms, Trojan horses, backdoors, root kits, spyware, and at times also bonnets, keystroke dialing attacks, spam, and phishing attacks.

Broadly talking, security includes data security, and thus computer network security software includes software with automatically backs up data. For yet greater security, backup can be done to an off-site location. Backup software can be set for the rate of backups and the location of the drive or server to which the backup is prepared. Data encryption can also add to data security.

In the area of defending the system from unwanted intruders, there are at least 4 roles that computer network security software can play. For 1 thing, one may consider a properly-configured web browser as security software, as the handling of cookies, passwords, downloads, attack sites, and web forgery contribute to the security of a system. Second, firewall software, on a computer, a router, a server, or all three, helps to stop intrusion. One can go still further with network scanning software, intrusion detection software, or a log-in system that only grants admission to the network to pre-approved individuals.

Network access to Internet technologies has proved to be helpful to organizations, including their employees, customers, suppliers, and business partners. This has not move toward about however without any increase in network security exposure and sharp competition for messaging resources. New capability such as intrusion detection, content screening, and URL blocking and bandwidth management has become obtainable. Service strategies give network security software products with firewalls and usage management software that allow companies to efficiently address these challenges.

Technical support for fixing computer network based security systems

Small and medium-sized businesses use the Internet and networked applications to get in touch with new customers and serve their existing ones more efficiently. on the same time, new security threats and legislation puts better pressure on business networks to be consistent and secure. Our technician delivers comprehensive, affordable, integrated security solutions help to ensure business continuity, maintain customer privacy, and reduce operating costs.
According to recent survey, security is the largest challenge facing. Ever-changing security threats from both inside and outside the network can cause confusion, affecting profitability and customer satisfaction.
Computer worms and viruses stay the most common security threat. Worms and viruses can have a destructive effect. Smarter, more critical strains are spreading faster than ever, infecting an entire computer in seconds. crackdown the infected computers takes much longer. The tragic results are lost orders, corrupted databases, and angry consumers. As consumer struggle to bring up to date their computers with the latest operating system patches and antivirus software, new viruses can go through their defenses any day of the week. in the meantime, the spread of viruses and spyware by unsuspectingly accessing malicious Websites, downloading untrustworthy material, or opening malicious e-mail attachments. These attacks are accidentally invited into the computer, but still cause major financial losses. Security systems must detect and prevent worms, viruses, and spyware at all points in the network.
 malicious hackers break into networks to steal credit card or social security numbers for profit.people are at risk because they are seen as an easier mark than huge corporations. Protecting the perimeter of the network is a excellent start, but it isn’t enough, since a lot of information thefts have help from a trusted insider. Information theft can be expensive since they rely on satisfied customers and a good reputation. People that don’t sufficiently protect their information could face harm.

There are few steps which are of huge significance keeping security of network in mind.
 bigger computer networks should be divided into segments for managing of the network and easiness in finding culprit systems. Internet access should be clean by blocking port1433 and port 1434 or one can use various firewall software to execute such type of filters. All unnecessary or not required ports should be blocked for any chance of being misused; only necessary communication ports should be unlock to data transfer.
 Keep nearer look on open ports, Port 80 is the most regularly used port for http access.                                   Network administrator should make sure to keep all the systems with server updated operating system files and latest patch. These dangerous updates and patch keep the system safe from vulnerabilities. at any time updates are free clients machines download and install them and secure them to the greatest level, same should be done for server operating system but keep nearer look in updating server OS. Third party security tools are also obtainable and can be installed after testing for meeting enhanced security measures.
Several times having a restricted Network administrators can help in keeping network safe as the less people manage the network less is the chances for security malfunctioning, it is also essential to not give any local client computer admin rights. Older known threats can attack another time, it should be kept in mind to keep computer network secure from newest ones should also be secured from older know attacks. Windows known services Telnet, Clipbook must not be disable, they have certain job to perform, do not disable any default service till the time you are sure about it and you also know that what are you doing. Creating, configuring and implementing security policies can be useful in keeping network secure. Keeping network users educated on these policies and making sure to send notice to all the clients if any updates are made in these policies. All these security actions are useful and come with prices. We should also frequently update network users for newest threats and what should and should not be done for keeping things smooth and secure. We must also help networks users to assist in unnecessary emails which can be dangerous to network.

Troubleshooting Network connectivity problems

In order to connect one computer to the other the most common problem that you generally face is network connectivity problem. This is a problem when you are not able to exchange information or data from your system to other systems. Depends upon the kind of problem, it is it can be temporary or long lasting. The most common reason why you face network problems is because, when your system is overloaded without any protection or with the physical damage to the system or it can be also because of the climatic change.

There are some various network connectivity problems:

1. Connection timeout: – this is because of the poor server performance, it occurs when you want to transfer or download the data and suddenly it stops working.

 

1. The other problem can be loss of connectivity that prevents you to get connected to the network. It can occur due to system crash and because of other reasons as well.

 

1. Improper connection: – when the plugs in the router are not connected properly and adapters and switchers are not connected properly.
2. Power outages: – due to power outages network connectivity can be lost.
3. Intermitted network connectivity: – This occurs when user gets disconnected to the network for a short interval of time and can cause internet breakdown.
