Do you know the importance of incorporating perimeter security solutions into your hotel networks? Are you aware of your security gaps in terms of unauthorized access to your network or computer systems? In this article we explain what perimeter security is, what benefits it provides and why you should reinforce it in your hotel.
What is the perimeter security of networks and systems?
Computer perimeter security consists of establishing a set of security controls around a technological structure, in order to guarantee adequate protection against attacks or access from intruders or unreliable networks.
Perimeter security systems include the following main elements:
firewalls
Firewalls or firewalls are devices that allow or deny passage based on a series of rules that specify what type of traffic is or is not allowed.
border routers
These are perimeter security equipment that act as if they were traffic signals that direct and control the movement of the networks, filtering out anything that is unreliable.
subnet protection
Small networks containing directly connected perimeter control utilities that offer protection by firewall or other filtering devices.
Intrusion Detection Systems (IDS)
It is an alarm system that serves to detect and notify about suspicious activities. There are two basic types of IDS: network-based (NIDS) such as Snort or Cisco Secure IDS, and host-based (HIDS) such as Tripwire or ISS BlackICE. The main difference is that NIDS sensors monitor network traffic for suspicious activity, while HIDS reside and monitor individual hosts.
Intrusion Prevention Systems (IPS))
These systems improve network perimeter security, since they not only detect intruders, but also immediately launch actions to defend the system, such as techniques for automatically blocking malicious traffic.

Anti-DDoS systems
Systems that automatically prevent or mitigate denial of service (DoS) attacks or distributed denial of service (DDoS) attacks, using a self-learning system, which serves to detect abnormal behavior in network traffic.
Managed antivirus and antispam gateways
Perimeter control mechanism that mitigates the risk of attacks by inspecting the organization's email accounts, in order to filter spam and malicious content, preventing them from entering the network and reaching the recipients.
VPNs and secure remote access
Secure remote access protects the transmission of sensitive data when applications are accessed from devices located outside the corporate network. To do this, they use different systems, such as VPN, virtual private networks connected through the Internet, protected by authentication and encryption methods.

Key points in the perimeter security of your hotel
Are you worried about the computer security of your hotel? Do you plan to implement a perimeter security system in the networks of your establishment, but do not know where to start? Below we explain, in depth, how to apply some perimeter security solutions in your hotel networks:
1. Firewall for hotels, key to your perimeter security
The main objective of firewalls is to protect us from possible computer attacks through early detection of malware or intrusion attempts. Its main advantage is that you can configure it according to your needs. For example, a firewall is used to segment the different types of networks: internal networks, guest WiFi or networks that provide services to professionals or occasional clients, such as event attendees. Firewalls are also used to manage and monitor the network, control the balance of lines or filter content or applications.

Likewise, it is possible to program a perimeter firewall to determine and control the type of traffic that is allowed in the networks of your hotel, in a coordinated and planned way.
2. VPN for corporate networks
The security strategy of a VPN is to organize protected and encrypted network sessions through a public and unprotected channel, such as the Internet. A VPN allows an external user to participate in the internal network as if they were directly connected to it. Its strong point is that it establishes an effective security perimeter, however it does not have the ability to control the connections of a guest in his room or, during teleworking, when an employee connects from home.
3. Prevention plan to protect access to servers
Do you want advice to protect the computer security of your hotel? Design a comprehensive prevention plan and implement a security suite that allows you to cover all possible flanks. In your perimeter security system you cannot miss, for example: IPS and IDS perimeter systems to control access to your hotel networks or the security of hosting services and servers.
In addition, you must protect yourself against cyber attacks on your website, email accounts and corporate Apps through firewalls and other IP blocking systems, access filtering with incorrect passwords, blocking of prohibited users and detection of DoS and DDoS attacks.
