Choosing the Best Server Racks for your Data Center

A well-chosen server rack will go along to ensure your data center is more efficient in terms of cooling, layout, and flexibility. Therefore, it is critical to treat your choice of server racks as a vital element of data center designing and planning. While selecting server racks, below are some of the main points you have to keep in mind.


Proper assembly of the rack and the strength of the materials that make the racks determine the server’s load capacity. It is not wise to consider a rack assembly as a trivial task. It is advisable to hire trained professionals to assemble the racks to avoid errors in the assembly, which can lead to structural damages or damage to the servers.

Open server racks are the easiest to assemble as they involve mounting rails meant to be attached. The ease of assembling the racks should not dictate your choice of server racks.

Overheating of the data center is the most common cause of damage to a server. The best way of reducing overheating in a data center is through ventilation. You can improve the airflow in a data center by choosing server racks with meshed front doors and rare perforated doors. It would help if you considered purchasing server racks with removable doors to quickly release hot air during an emergency. If you are working under a tight budget, you can consider installing a fan above the servers to keep them cool. Open server racks with rails supporting servers are ideal if ventilation is your crucial requirement. However, for servers to be protected by enclosures, you can choose top-cooled racks with dedicated and precision cooling units for each server.

Ease of Customization

Off-the-shelf server racks offer your desired flexibility, and this is where you will need to customize your rack. Depending on the server and other data center elements, a custom-built server rack may help you optimize ventilation and adjustability, giving your data center the much-needed business edge.

Your rack system must allow for easy accessibility, adjustability, and flexibility, which are essential for the data center design plan. You need to inspect the kind of cables and servers that will make the data center and optimize the racks so that accessibility and connectivity are not compromised.

A data center is a crucial part of your business, and ensuring it is at its best should be a priority when planning and designing the data center.…

How to Choose the Best Firewall Features for Your Business

As businesses evolve into digital workplaces, cyber-attacks and data have become a common occurrence — the first step that most people take to counter this is knowing how to respond to a cyber-attack. However, that is not effective enough without having the best firewall.

A good firewall like sonicwall firewall to protect your business is typically a protective barrier (hardware) placed between the public internet and your internal network to prevent intrusions from entering your system. It functions by scanning traffic going in and out of your system as well as prevent malicious attacks from entering.

The pressures and complexities that surround choosing the best firewall is an issue to many business professionals. The struggle of picking the right one is as a result of the different features it offers. Below, is a list of top features of a firewall that you should consider before choosing one.

Robust Protection Against Malicious Attacks

A firewall will only be worth your hard-earned money if it has the capability of protecting your network from compromising threats. These threats include DDoS attacks and malicious hackers. Additionally, it should also scan for threats in traffic to and from applications within your system.

Real-Time Alerts

Technology is now making every process to be in real-time. A real-time feature is essential to any firewall. The feature will provide you with real-time updates of any attack that is in progress. Through this, you can combat the malicious attack before it spreads to the whole network.

Remote Access

The firewall that you’ll select should provide you with control and remote access to your site. The remote access is essential for businesses having employees working from home or multiple offices. Therefore, ensure it allows client-based VPN and site to site tunnels.

Spam and Website Filtering

The feature enables you to block websites based on individual website names and categories. It is an ideal feature in the case where you know some malicious sites. Additionally, it also performs spam filtering functions as well as inspecting the traffic coming through your email.


It is the latest firewall feature innovation. The feature prevents access to malicious access to malicious content found in links. The feature monitors the link after a user clicks on it, and if the link turns out to be malicious, the feature sends a signal to the firewall. The firewall will then block the file and proceeds to stop it from being downloaded.

Inspection of Encrypted Traffic

firewall securityIt is an essential feature since most cyber attackers use encrypted traffic. The feature inspects SSL encrypted traffic. Firewalls with this feature capture the encrypted traffic as it comes into your network, then decrypt it and read it to ensure it is what it says it is. Finally, it re-encrypts and sends it back out. The whole process is accomplished by using the same SSL certificate.

Wireless control

The feature allows controlling wireless internet access and wireless access points connected to the firewall. With this feature, it will enable safe and protected wireless connections from smartphones, tablets, wireless printers, and tablets. It is an essential feature for businesses operating at a big working place or different geographical locations.…

Important Steps for ISO 27001 Implementation

Starters in ISO 27001 implementation may probably be looking for an easy way of implementing it. There is no easy way of doing this. You can, however, follow some steps to make the process better. Here are some of the steps you must go through if you need to achieve ISO 27002 certification.

Obtain Management Support

This is rather obvious, and it is normally not taken seriously enough. It is, however, the main reason why ISO 27001 projects fail. Management does not provide enough people to work on the project or enough resources. You, therefore, need to the support of the management first.

Write an ISMS Policy

This is a high-level document in your ISMS. It should not be very detailed but need to define some basic issues for information security in the organization. Its purpose is for management to define what to achieve and how to control it.

Define Risk Assessment Methodology

The point here is to define the rules for identifying vulnerabilities, assets, threats, likelihood and impacts, and define acceptable risk level. If these rules are not defined clearly, you may find yourself in a situation where you get unusable results.

Perform Risk Assessment and Treatment

Here you must implement what is defined in the previous step. It can take several months for big organizations, so you need to coordinate such efforts with care. The point is to get a clear picture of the dangers of the organization’s information.

The purpose of risk this process is to reduce the risks that are not acceptable. Here risk assessment report is written. This documents all steps taken during the risk assessment and treatment process. An approval of residual risks must also be obtained

Write the Statement of Applicability

After the risk treatment process, you know the exact controls you need. The purpose of this document is to list all controls and define which ones are applicable and which ones are not, and the reasons for such decisions, objectives to be achieved and how they are implemented. This is the most suitable document for obtaining management authorization for ISMS implementation.

Risk Treatment Plan

This document defines how the controls from the scalability of applicability are to be implemented. It is an implementation plan focused on the controls without which you will not be able to coordinate further steps in the project.

Implement the Controls

security awarenessThis is the riskiest part of the project. It means the application of new technology and implementation of new behavior in the organization. New procedures and policies are required, and people tend to resist change, so they need training and awareness.

Implement Training and Awareness Programs

You need first to explain your personnel why the procedures and policies are necessary if you want them to implement the policies. The absence of such programs is the second most reason for the failure of ISO 27001 projects.

After this, you can now, operate and monitor the ISMS. Internal audit, management review and corrective and preventive action will follow after that. Following these steps will help you the ISO 27001 implementation.…
