You can also set spending limits and employ cost management tools to prevent overspending.

Why does Microsoft Azure matter?

Azure, like other cloud service providers, offers the ability to instantly provision computing resources on demand. Compared to the onerous task of planning and building an on-site data center, along with the requisite hardware upgrades, maintenance costs, server cooling requirements, electricity costs, and use of floor space — particularly for offices with associated real estate costs — the savings can add up very quickly.

The benefits of Azure extend beyond cost control, however. The task of administering certain technologies, such as Windows Server, Active Directory, and SharePoint can be greatly eased with the combination of Azure and Office 365. This frees up IT staff to work on new projects, rather than spending time on general system upkeep.

Who does Microsoft Azure affect?

Organizations with an existing deployment of Microsoft technologies, particularly Windows Server and Active Directory, will find Azure to be a compelling upgrade. As Windows Server 2008 has reached the end of mainstream support, planning for a migration to cloud-hosted Azure services may be preferable to investments in new server hardware and Windows Server licenses.

As with any cloud service, the cost benefit is more real for cash-strapped startup organizations that lack the capital for provisioning hardware and associated costs of a traditional on-premise deployment or leasing dedicated servers in a traditional data center. Because the billing structure of Azure is based on resources used, turning to the cloud allows a company’s IT backbone to scale with corporate growth.

PSL’s Easy Guide to Understanding Cybersecurity

The world of cybersecurity can often feel like a maze of technobabble and obscure acronyms. Yet in an era where our lives increasingly depend on digital infrastructure, it's important to have a basic understanding of the terminology involved. Learning about cybersecurity can help you avoid common mistakes and limit the chance of becoming a victim of these crimes.

Here is an overview of common cybersecurity terms.

1) Cybersecurity

Let's start with the basics. Cybersecurity is simply the defense against digital attacks that target computers, mobile devices, networks, and servers. These attacks are typically aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business processes.

2) Malware

Malware is any malicious software that can damage or infiltrate computers without the user's consent.

Here are the most well-known types of malware.

Virus

Like a biological virus, a computer virus attaches itself to a host (in this case, a file), and spreads when the file is shared, infecting other files and systems.

Worm

A worm is a standalone type of malware that will replicate itself to easily spread to other computers through a network.

Trojan

Named after the Greek myth, the Trojan horse, a Trojan is a form of malware that attempts to disguise itself as a normal program or file to trick users into either downloading or installing it.

Ransomware

This type of malware encrypts the user's files and demands payment to unlock them.

Spyware

Spyware is malware that's specifically designed to spy on user activity without their knowledge.

3) Phishing

Phishing is a common attack that tries to gain personal information by using deceptive emails and websites. The attacker, masquerading as a trustworthy entity, uses a variety of strategies to trick the victim into opening an instant message, email, or text message.

4) Firewall

A firewall is an IT security tool that controls network traffic using predetermined security rules. Think of it as a digital barrier limiting unauthorized access to your network or computer.

5) VPN (Virtual Private Network)

A VPN masks your internet protocol (IP) address to make your online actions nearly untraceable. VPN services establish encrypted connections to provide much greater privacy while using the internet.

6) Encryption

Encryption converts data into a code to prevent unauthorized access. When data is encrypted, it appears as gibberish unless you have the decryption key to convert it back to its original form.

7) Two-Factor Authentication (2FA)

2FA is a common security process in which users must provide two different authentication factors to gain access to an account. For example, in addition to a password, you might also need to enter a code sent to your phone.

8) Darknet/Dark Web

The darknet or dark web refers to encrypted online networks that aren't indexed by search engines, and they are often used for illicit activities. You need special software (like Tor) to access it.

9) Data Breach

A data breach happens whenever secure or private information is released into an untrusted environment. This is often due to a cyberattack on a database, leading to sensitive data being exposed, copied, or used.

10) Botnet

A botnet uses a group of private computers that are unknowingly infected with malicious software and are controlled as a group to perform various tasks. Many times botnets are created to send out spam emails or carry out Distributed Denial of Service (DDoS) attacks.

Closing Thoughts

Understanding cybersecurity is not just for the tech-savvy; it's for everyone. We are all potential targets for cyber threats, and comprehension of basic cybersecurity terminology can make a significant difference in safeguarding ourselves and our digital assets.

Employing cybersecurity measures also helps to keep your digital data safe. This might include using a VPN, enabling two-factor authentication, or simply being wary of suspicious emails to prevent phishing attacks.
