Why server security is important

If your business is like most, you rely on technology to keep things running smoothly. Servers are critical components of any company’s IT infrastructure, so it’s essential to ensure they’re secure. Unfortunately, many businesses don’t take the necessary precautions to protect their servers from attack. Here are just a few reasons why server security is so important:

1) A breach can damage your reputation and cost you, customers.

2) It can expose your confidential data and put your customers’ information at risk.

3) It can leave your systems vulnerable to further attacks.

4) It can be expensive to recover from a data breach.

5) The consequences of a breach can be far-reaching and long


With the introduction of new technologies and services, it is vital to keep your server up-to-date so that you can maintain an advantage over other companies. There is always a fine line when making your server services easily accessible and secure. Security vulnerabilities will always be present when opening a communication system, leading to many risks such as hacking websites or publishing desktop clients online without proper protection against cybercriminals who want nothing more than misinformation on their hands.


Open TCP/IP ports can be an invitation to hackers, especially if they’re well-known ports such as Remote Desktop Protocol, MS SQL Protocols, SMB Protocols or Web Service Protocols. Attackers will target these ports, which are often unmonitored by system administrators, allowing intruders to take advantage of these ports if they are open.

What does the attacker do once they access the system?

These attacks are classified as malicious activity or policy violations on your servers.

The most common purposes of intrusion attacks are to:

  • Gain unauthorised access to files, privileges, data or money
  • Destabilise a network for financial or personal gaain
  • Use software beyond what policy permits

How can I prevent these attacks – IP Warden

IP Warden is a Host Intrusion Prevention tool that monitors the Windows Event logs for unsuccessful login attempts from any given source IP. IP Warden firstly watches the Windows Event Logs for authentication logs and identifies unauthenticated attempts.


After your specified number of login attempts is exceeded, the offending source IP is then added to a custom IP Warden firewall rule within the Windows firewall. This allows any further activity from the offending IP to be blocked on the Windows Firewall level to the server.


IP Warden can monitor Remote Desktop, IIS, SMB (File and Printer Sharing) and MSSQL. The product is still developing, and we have more services planned for the near future.

What is IP Warden?

IP Warden is a host intrusion prevention tool that monitors the Windows Event logs for unsuccessful login attempts from any given source IP. IP Warden firstly watches the Windows Event Logs for authentication logs and identifies unauthenticated attempts. It then blocks the IP address from which the attempt originated, preventing any further attempts.


IP Warden is an essential tool for businesses that rely on Windows Event Logs for security purposes. By blocking IP addresses that attempt to access event logs without authentication, IP Warden helps prevent data breaches and safeguard businesses. In addition, IP Warden can be configured to send notifications whenever an attempt is made to access event logs without authentication, providing companies with an extra layer of protection.

Most people are aware that they need some security measures in place to protect their computers from viruses and other malicious software. However, many people think that a firewall and antivirus program is all they need. Unfortunately, this is not the case. Firewalls and antivirus programs are essential, but they are not enough to protect your computer from all threats. Intrusion prevention security updates are also important. These updates allow the mitigation of vulnerabilities, but attacks are often not targeting exploits.


Firewalls can also not prevent intrusion attacks. Firewalls look outwardly for intrusions and do not block an attack from inside a network. They analyse, filter, or block external traffic to access your internal network. To be truly safe, you need all three of these security measures in place.


Policies should be reviewed, and permissions and privileges can create barriers to these attacks. In addition to this, you should be considering intrusion prevention detection (IPD) and intrusion prevention systems (IPS). These solutions analyse traffic for threat signatures or anomalies in network traffic, either monitoring or controlling the traffic.

How can I prevent these attacks

Prevention

IP blocking is an essential security measure that can help to prevent malicious attacks before they occur. By blocking IP addresses that have been associated with failed login attempts, you can help to ensure that only authorised users can access your system. With IP Warden in place, you can rest assured that your system is better protected against unauthorised access.


Data Security

IP warden provides various features to keep your data safe from malicious users. By using IP warden, you can help ensure that your data remains secure and out of the hands of malicious users.


Reliability

IP Warden is a service that runs in the background, ensuring all login attempts are monitored. IP Warden will block the login attempt and notify the administrator if the IP is not in the database. This allows you to rest assured that only authorised users can access your system.


Features include

DYNAMIC IP BLOCKING

IP addresses are a vital part of the internet. However, IP addresses can also be used to launch attacks against websites and online services. This technology prevents the originating IP address from submitting requests after a specified number of failed login attempts using incorrect usernames or passwords. As a result, dynamic IP blocking can help to thwart malicious activity and keep data safe.

BLOCK ACCORDING TO ACCESS TYPE

IP Warden allows the blocking of specific service types such as RDP, IIS, MS SQL and SMB. Blocks the selected type of traffic according to an access type. IP address blocking can be used to restrict access.

MANUAL IP BLOCKING

IP Warden can help you quickly manually block IP addresses with our IP blocking feature. Simply add the IP addresses you want to be blocked in the IP Warden interface, and our system will automatically block all traffic from those IP addresses.


CUSTOMISE MONITORED PORTS

Allocate which ports are being used. To customise monitored ports and allocate which ports are being used by your server services and monitored with IP warden, businesses can identify which ports are most attacked by offenders. By taking this approach, businesses can ensure that they have the knowledge and visibility necessary to protect their operations from potential threats.


MAX IP BLOCKS THRESHOLD

You can set the maximum number of IP addresses blocked on a server. To do this, simply navigate to the “Block Settings” section of your server’s control panel and enter the desired number into the “Max IPs” field. Once you have saved your changes, all new attempts to access your server from an IP address that is already blocked will be automatically rejected.

SMTP NOTIFICATIONS

Do you need to be notified by email when an IP address is blocked? Our system will send you an email notification whenever an IP address is blocked. This way, you can stay on top of any potential issues and take action accordingly. There’s no need to worry about keeping track of IP addresses yourself – we’ll do it for you.


LAST LOGIN USERNAME

The last logon is a server security feature that displays the previous username used to attempt to gain access to the server. This information can help determine if unauthorised access has been tried and can help track down the source of the intrusion. In addition, the last logon can also help to identify user accounts that are no longer in use, which can be disabled or deleted to free up resources.


PERMANENT / TEMPORARY BAN TIMES

Set if you want to permanently block IP’s, or if you allow a timeout and allow offending IP’s to connect again after a timeout is reached. A perma-ban never expires.


WHITELISTING BASED ON DNS NAME OR IP ADDRESS

Whitelist DNS names and IP addresses so that they are never blocked. Whitelisting creates explicit firewall rules to block all IP addresses and only allows specific IP or DNS addresses should you wish to do so. IP Warden does continuous DNS lookups to ensure that firewall rules are updated even if DNS record IP addresses change. This means that you can even whitelist Dynamic DNS addresses.

HOSTNAME LOOKUPS

This Hostname Lookup tool, often referred to as hostname lookup, looks up the Hostname of the blocked IP Address—a simple yet very effective tool for getting the hostname information you need.
