What's cyber security?

Computer security, cybersecurity or information technology security (IT security) is the security of computer systems in the theft of or damage to their own hardware, applications, or digital information, in addition to in the disruption or misdirection of their solutions they supply. The area is becoming more important because of greater reliance on computer technologies, the web and wireless system standards like Bluetooth and Wi-Fi, and as a result of development of "smart" devices, such as televisions, smartphones, and the numerous devices which constitute the"Internet of things". Due to its complexity, both regarding science and politics, cybersecurity can also be one of the significant challenges in the modern world.

What's cyber security?

Organizations face many threats to their data systems and information. Knowing all of the fundamental elements to cyber safety is the first step to fulfilling these threats.

Types of cyber security.

The reach of cyber protection is broad. The core regions are explained below, and some other fantastic cyber security plan must take all of them into consideration.

Critical infrastructure includes the cyber-physical systems which society is based on, for example, electricity grid, water purification, traffic lighting and hospitals. Plugging a power plant to the world wide web, as an instance, makes it vulnerable to cyber attacks. The solution for associations accountable for critical infrastructure would be to carry out due diligence to safeguard recognize the vulnerabilities and protect from them. Everyone else must evaluate the way an attack on critical infrastructure that they rely on could impact them and develop a contingency plan.

Network security guards against malicious intrusion in addition to malicious insiders. Ensuring network security frequently requires trade-offs. By way of instance, access controls like additional logins may be required, but slow down productivity. Tools used to track network safety create a great deal of information -- so much that legitimate alarms are often overlooked. To help better handle network security monitoring, safety teams are using machine learning how to flag abnormal traffic and alert to risks in real time.

Application security (AppSec), especially web application security, has become the weakest technical point of attack, but few organizations adequately mitigate all the OWASP Top Ten web vulnerabilities. AppSec begins with secure coding practices, and should be augmented by fuzzing and penetration testing. Rapid application development and deployment to the cloud has seen the advent of DevOps as a new discipline. DevOps teams typically prioritize business needs over security, a focus that will likely change given the proliferation of threats.

IoT describes a huge array of crucial and non-critical cyber physiological systems, such as appliances, sensors, printers and safety cameras. IoT devices often ship in an insecure condition and give little to no security, posing risks to not just their customers, but also to other people online, since these devices frequently find themselves part of a botnet. This presents special security challenges for the home users and society.

The Apache HTTP Server—known as Apache web server or simply Apache—is considered the standard for general-purpose HTTP activities and services. It offers a wide range of modules to deliver optimum flexibility in support of URL rewriting, proxy servers, and granular access management and control. Apache is a popular choice among web developers because it uses CGI, embedded interpreters, and FastCGI to support server-side scripting. This allows for the rapid and effective execution and implementation of highly dynamic coding.

There are plenty of well-known Apache alternatives—nginx, XAMPP, Caddy, and Microsoft IIS, among many others—but none of them offer the same breadth of usage provided by Apache. Apache is so widely used it has more than a 50% share in the commercial web server marketplace. It’s especially popular for use with Unix-like operating systems, although it supports most platforms. This includes Windows, OS X, OS/2, and others.

However, Apache’s flexibility and breadth of usage come at the expense of simplicity in many cases. The configuration structure is complex, and many of the advanced functionalities are difficult to use. This Apache server tutorial will explain the basics of Apache, providing instructions for Apache web server configuration in Linux, step by step. The aim is to help you not only set up Apache server, but also monitor it. My recommended tool for this purpose is SolarWinds® Server & Application Monitor for Apache.

A Simple Definition of Apache

Apache is a process-based, modular, open-source web server application designed to establish a new thread for each connection occurring simultaneously. Apache supports a range of functionalities, covering everything from authentication mechanisms to server-side programming languages. It also supports virtual hosting, allowing you to use one Apache web server to serve multiple websites. Most Apache capabilities are delivered as individual modules, allowing you to extend and enhance Apache’s core utilities.

How to Set Up Apache Server

You may find yourself becoming overwhelmed as you start to set up Apache server. As an open source, advanced application capable of a wide range of functions, Apache web server configuration and setup is fairly complex.

You can install and set up Apache server in two ways.

  1. Vendor-based installation. As it’s an open source web application, anyone can make an installer to suit their individual environment. Vendors like Red Hat, SUSE, and Debian have used this capability to customize Apache server configuration and file location by taking the base operating system and other installed programs into account.
  2. Source code installation. The alternative to using a vendor-based installer is to set up Apache server by building and installing directly from the source code. This approach enables you to set up Apache server in platform-independent manner available for all operating systems.

With both installation options, modules can be compiled in the form of a dynamic shared object, or DSO. A DSO is an object file capable of being shared and utilized by numerous applications. DSO modules are separate from the core Apache file. The DSO approach to compiling modules is popular because it makes adding, updating, and removing modules easy.

How to Set Up Apache Server in Linux

This Apache server tutorial will now provide instructions for Apache web server configuration in Linux, step by step.

  1. Update your system repositories. This involves downloading the most recent version of a software by updating the Ubuntu repositories’ local package index. To do this, go to the terminal and enter the command “$ sudo apt update” into it.
  2. Install Apache by using the “apt” command. For this example, let’s use Apache2. Just input the following command— “$ sudo apt install apache2” —as sudo, which will install Apache2 and all necessary dependencies. At this stage, you may be asked whether you want to continue the installation process. Enter “Y” to indicate you would like to, and installation will begin.
  3. Verify Apache has been successfully installed. When the installation procedure has finished, check the version number to confirm Apache2 is now installed on your system. Enter “$ apache2 -version” to do this. The server version will appear, hopefully confirming Apache2 has been installed.

How to Set Up Apache Virtual Servers

When using virtual hosts, it’s important to undertake virtual server Apache configuration. Modifying configuration settings will ensure they reflect the domain specifics, which will allow Apache to respond to domain requests correctly and successfully. The process for completing virtual server Apache configuration is simple:

  1. First, input “$ sudo nano /etc/apache2/sites-available/example.com.conf” to open your virtual host configuration file.
  2. Replace “example.com” appropriately. Next, you’ll be able to modify the following:
    ServerName example.com
    ServerAdmin This email address is being protected from spambots. You need JavaScript enabled to view it.
    ServerAlias www.example.com
    DocumentRoot /var/www/example.com/public_htmlAgain, be sure to replace all example components with the appropriate information. When modified, the end result should resemble the following:
    <VirtualHost *:80>
    ServerName example.com
    ServerAdmin This email address is being protected from spambots. You need JavaScript enabled to view it.
    ServerAlias www.example.com
    DocumentRoot /var/www/example.com/public_html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
    </VirtualHost>
  3. If an error occurs, reference these instructions to ensure nothing has been mistyped or inputted incorrectly.

Best Apache Server Monitoring Tool

After setting up Apache web server, I highly recommend the use of a monitoring tool to help you test Apache server and monitor it effectively. There are several such tools on the market, but SolarWinds Server & Application Monitor (SAM) tops my list. This tool allows you to easily define specific performance metrics to facilitate proactive monitoring of Apache Cassandra, Apache Geronimo, and Apache Tomcat. The single application is capable of monitoring and managing your entire Apache environment, and the underlying infrastructure of the server.

With SAM, monitoring uptime and performance is easy, as is diagnosing the root of performance issues. The application facilitates proactive monitoring of all web server supporting components contributing to the Apache web server, including Linux and MySQL. Application monitoring covers the virtual layer, servers, and applications like Microsoft SQL Server, Exchange, and Active Directory. The system benefits from customizable alerts, reports, and easy-to-navigate dashboards ready to use out of the box. This means you can get up and running when SAM is installed, without having to create or modify dashboards.

The dashboards themselves have been cleverly designed, with data represented in the form of graphs and charts whenever appropriate, to give you immediate insight into key metrics and information without overloading or cluttering the interface.

SAM is a scalable and highly feature-rich application, requiring zero training or experience to start using, and is suitable for extensive enterprise-grade requirements. The user-friendly interface is one of SAM’s best features, as it makes data interpretation dynamic and accurate. This program simplifies the Apache monitoring experience, allowing you to test and interrogate it in a few simple clicks. The implementation process is simple, and SolarWinds support technicians are available on a 24/7 basis.
