Server Management

group of young business people it engineer in network server rooSome people may tell that managing a server is very easy while others will tell that they are very hard but actually the matter of fact is that what management plan you are using which will widely deploy visualization. Management is not a single act but a series of acts that will combine together to do the perfect management. Standardization and Consistency are a very big problem as maintaining the same level is very difficult. Beyond availability, management or security another important thing is performance. The various management tools are as follows.

Sysinternals Suite: If you are new to the windows or IT platform this is a very handy tool as this is a super valuable and easy set of tools. Various SYSinternals Tool are possible to run from the website directly which does not need any installation.

Spiceworks: This was released on 2006 and many richmond IT professionals are using this provides change management, monitoring, inventory management, IT help desk and virtualization management.

Wireshark: Its former name is Ethereal. Sometimes there will be many hard questions then Wireshark can help you to manage the network traffic and find the answer.

Wake-On-LAN: it does the work as its name implies of sending packets through the network if your PCs have Wake-On-LAN. It requires the IP address and MAC address of the remote system which you want to boot.

Viewfinite Local Admin Discovery: Sometimes it is a problem to manage the admin rights. Viewfinite Local Admin Discovery helps to find all the users which are given the authorization of the admin group.

Remote Desktop Manager: We need a lot of management to do and this can be done by RDP Remote Desktop Connections. Many RDP connections cluster up which needs different settings for all and personalized authentication. Remote Desktop Manager helps you to categories all the remote connections, credentials and passwords separately.

Security Threats

Internet Security And Malware Threats, Bomb Inside PcNowadays anyone and everyone can set up a server. It is very easy task and you can start your server in your basement and can publish websites. Moreover, many companies give leased servers and VPNs at a very reasonable price. This shows that anyone with or without experience can also start a server whenever they want. They may not be even trained in that sector. For these kind of people there are many blogs or forums where they can join and learn all about the servers. But knowing all this there are some threats which all face irrespective of your trained or not. They many threats are as follows.

Brute Force Attack: This is a kind of attack in which the hacker or intruder tries to gain access into a server by guessing all the possible combinations of the password through the mail server, SSH server or other running services. They usually use software that check all possible combinations and find out that matches. Brute Force attack gives you an alert message that there are multiple failed authentication and thus disabling the hackers IP address.

Botnet: Botnet is a software that automatically executes and distributes software that are malicious and so attackers use these to spread malicious software on server machines. This way they try to infect all the machines that are connected to that server machine. As no human intervention is required in this type of attack, it is widely used to spread malicious software very quickly and this can be very deadly for large networks.

Open Relay: A MTA or Mail Transfer Agent sends mail with the help of an SMTP server from the server you are using to all the people. With the help of Open Relay anyone can use the SMTP server which also includes spammers. This increases the risk of a third party who will have access to block emails from your IP address but this is nothing to worry about as it is easy to close Open Relay.

DoS: It stands for Denial of Service. In this way of attacking the attacker blocks your site and no one can access your website. They do this by increasing the amount of traffic in your website so that it becomes non responsive and no one can access it any more. Generally, DoS attacks are done by single attackers but also sometimes from a coordinated group of people and maybe sometime people might not know that they are acting as a member of a group for DoS attacks.

Malware: Malware is a malicious software that may take multiple forms to attack a server. It can be anything like Trojan, bots, viruses, spyware, worms, rootkit and many other which has the intension to do harm. Malware is generally installed without the user even knowing that the software is installed or getting installed at that particular moment. You can prevent the malware to spread or affect your system you can install firewalls and other software security methods.

Cross-site Scripting: This uses the vulnerability of the web applications and is also known as XSS technique. In this the attacker launches a software in the server side that will process the harmful programs and extract important data from the user.

Various security measures to protect your servers

Online paymentIn today’s world cyber theft has taken a toll and only being able to put up your program and make it run is not the sole criteria. Your application should be safe and well-guarded from the cyber thieves and this can be done by the various ways of server protection techniques. Below are the various security measures that you should configure your applications with before you run it online.

SSH keys: SSH keys are an alternative to logins which are password based. They are actually a pair of keys which are cryptographic that are used to authenticate an SSH server without a password based login. Before authenticating 2 keys are generated, a private key and a public key. The public key is known by everyone and the private key is kept secret. The public key has to be kept in a special directory for authenticating with SSH key authentication. When a user connects to a server, the client has to show proof to the server that he or she has the associated private key. If the private key matches, then the user can connect to the server without the need of a password. SSH key authentication lets you run a password free authentication and is much more secure because passwords are less bit codes and latest technology has made it possible for hardware or software to hack into the server by giving all possible codes until the correct code is obtained. In SSH key encryption, the keys are very large bit entities and still now technology has not made it possible to hack such large bits of code. They will take a lot of time to find the correct combination which is practically impossible.

Firewalls: Restricting access from user over some ports and allowing access on some which are supposed to be public is done by Firewalls. It is a piece of hardware or software that monitors and controls the services to a network. There are internet services that can only be accessed from within a server and not exposing the services to the whole world. There are some private services also where the server is only accessible to authorized persons only or public services where everyone can access whoever is using the internet from any account or any location. Firewalls are very important part of the configuration of a server. Though services have security features but firewalls provide an extra level of protection to your servers.

Private Networking and VPNs: Networks that are only available to fixed users or servers are called Private Networks. VPN are networks that shows the connections are locally connected but in reality the computers are located remotely. This allows secure connection of remote users or servers and configure the entities as Private Network. Securing by VPN allows you to access databases that can only be visible by your servers. Fully secure and private communication. VPN initial setup is a bit complex than the others but it is worth because it gives more security.

PKI and SSL/TSL Encryption: PKI or Public Key Infrastructure is used to manage, create or validate for encrypting communications and identifying individuals. SSL/TCL are used to authenticate multiple entities with one another. When the authentication is done it can be used to encrypt the communication.

Service Auditing: Still now we discussed how to improve the security by encryptions and authenticating the user but security also is about analyzing your systems and finding out the possible weak areas and closing them so that attacks does not happen. This is the way to find the flaws in your own servers and fixing them.

Intrusion detection systems: IDS is a software which keeps track of who are entering your server or using the services of your server and checks that they are authorized or not. Generally, they use file auditing systems for checking the change in the system.

Isolation Execution Environments: It is a method where individual components are made to run in their own space. This is done to separate components to respective servers.
