What Is Cloud Security?

Cloud security is also commonly known as cloud computing security and is made up of a set of policies, procedures, technologies, and controls that work to protect systems in the cloud, infrastructure, and data.

Cloud security focuses on making sure every aspect of your network that interacts with the cloud is safe and that your cloud infrastructure remains well-protected from security threats.

 

Why Is Cloud Security Important?

Every time there is a security breach in the cloud, companies lose money, time, and resources as they try to recover. The downtime that results from a cloud breach can cause significant operational setbacks, and cloud-connected devices and networks can be exposed to a variety of threats.

While maintaining a security system for an in-house network is often managed by an internal IT team, whenever you put data or systems on the cloud, your valuable digital assets are, essentially, under someone else’s care. To minimize the resulting inherent risk, a robust cloud security system is necessary.

Here are just a few of the benefits of cloud security:

 

Safer Remote Work Environment

One of the top advantages of incorporating cloud computing into your operations is data accessibility. Anytime an employee has an internet connection, they can interact with the content or systems they need to do their jobs. This gives your company flexibility and agility.

A problem may arise, however, if employees access your cloud infrastructure through unsafe means. For example, if someone slips into a coffee shop, they may sign in using a public network. This leaves your cloud network exposed to any bad actors who may be looking for opportunities on that public, vulnerable connection.

Also, when employees use their personal devices—or take devices from work home with them—they can accidentally expose them to malicious software. When they connect to your cloud environment, anything that sneaked onto their computer or device—such as malware or Trojans—could be used to invade your cloud system.

The only way to guard against these kinds of inroads into your infrastructure is to institute a powerful cloud security system.

 

Ensure Safer Stores of Data

Many companies use a cloud environment to back up their data. In the event of a disaster, it is easy to get things up and running because all you have to do is connect to the cloud and grab what you need. However, if this data is not secure, you could end up downloading corrupted files. If these were allowed to penetrate your system, they could affect not just your business’s network and devices but those of customers as well.

A cloud data security system helps shield valuable data from dangerous software, organizations, or people.

 

Meet Regulatory Requirements

In certain sectors, the degree to which you keep data secure can determine whether you are on the right or wrong side of the law. For example, with current Health Insurance Portability and Accountability Act (HIPAA) and General Data Protection Regulation (GDPR) laws, a lax security system could result in the exposure of sensitive data—to the extent that you fall out of line with current legislation.

A strong cloud security solution can help you prevent a security slip-up from having serious legal ramifications for your company. This is especially important in light of the fact that those who enforce the law often feel obligated to find someone to blame when things go wrong. A security breach could put your organization in the crosshairs, resulting in bad press, legal battles, and lost shareholder confidence. On the other hand, a complete cloud data security system could prevent problems before they begin.

 

Keep Data in and Attackers Out

A cloud system without thorough security measures in place can be like a data sieve. With so many users accessing the network via a wide selection of devices, it is easy for data to get leaked to the wrong person. Additionally, an unprotected cloud system is a convenient attack surface for hackers.

A cloud security system acts like the door to a vault. It keeps valuable data inside while keeping criminal elements out.

 

 

Cloud Computing Categories

  1. Public cloud services: A public cloud is one managed by a third-party provider. The space on the cloud server is rented to organizations, and the third party is in charge of maintenance, security, and general upkeep.
  2. Private clouds: A private cloud is limited for use by a single organization. The resources and infrastructure are used exclusively by that company. These tend to come with a higher price tag but offer better customization and security options.
  3. Hybrid clouds: A hybrid cloud works as a combination of public and private cloud features. Companies that want the freedom to scale quickly as well as enjoy strong security often take advantage of hybrid cloud services.

 

Cloud Computing Security Challenges

  1. DDoS attacks: Distributed denial-of-service (DDoS) attacks have been growing in popularity. Attackers use DDoS attacks to overwhelm a website’s server so it does not have the capacity to respond to user requests. This could render the site useless for long periods of time.
  2. Loss of data: Data can be lost from the cloud for a variety of reasons. Even when no one is actively trying to take data, it can be lost due to an accident or a natural disaster. Not only do cloud security solutions help keep thieves out but they can also include measures to protect data from unexpected events.
  3. Data breaches: Data on the cloud can be a slow-moving target for the right hacker if it is not secured. Some steal data to exploit members of an organization. Others sell it to entities wishing to know a company’s secrets. Without the right cloud security solutions, a company’s data may be exposed.
  4. Vulnerable access points: A cloud-based system offers unbeatable access, but the devices used to interact with the cloud are often unprotected or under-protected. As a result, nearly every phone, tablet, laptop, or other mobile device that accesses your cloud system could present an attack opportunity for the wrong person or software. However, with the right firewall, you can limit access to the right kind of traffic.
  5. Alerts and notifications: When there is a security breach, stopping the threat before it does significant damage is only part of the job. A complete system will make sure important stakeholders are notified of the situation. Often, the damage of an attack, even after it has been stopped, comes from the fact that too much time passes before the IT team is able to react and alert others. A responsive cloud security system provides information through alerts and notifications to those who need to know—and when they need to know it.

 

Cloud Security Best Practices

  1. Put data protection policies in place: Each organization has mission-critical data that needs to be protected. It is important to identify the most crucial data and shield it from unwanted access. Minimizing the attack surface of crucial data can focus your cloud security resources, enabling you to get the most out of them.
  2. Use personalized keys to encrypt sensitive data: Even the strongest username and password combination can be compromised by an enterprising hacker. Whether an outsider uses spyware or a disgruntled employee gets their hands on login credentials, breaches in single-factor authentication models are far too easy to orchestrate. With multi-factor authentication (MFA) using personalized keys, your system is better protected.
  3. Limit how data gets shared: With multiple users sending data to various people, it can be difficult to pin down who is getting what and how. Customers, investors, and other outsiders may gain access to sensitive data unnecessarily. You can use a cloud security system to make sure only those who “need to know” can access sensitive data.
  4. Prevent data from going to unmanaged devices: It is important to know how data is treated after it leaves your cloud. A number of unmanaged devices could result in data being shared with the wrong parties. However, with a cloud security system, you can make sure only the right devices connect to the network.
  5. Data encryption in the cloud: Encrypting data provides an extra layer of protection. Even if someone is able to get behind a firewall or web filter, the encryption hiding the data can still keep your data safe.
  6. Routinely test your security system: Having a powerful system in place is only half the battle. To ensure its functionality, you should have penetration tests performed. This can reveal critical gaps that you can address through additional measures or adjustments to your security setup.
  7. Train the necessary employees to support your security system: Employees are often a security blind spot. Even though they may have the best intentions, a small error can be disastrous for your cloud security setup. Training them on what to do, what not to do, how to manage their access keys, and things to look out for can eliminate potentially costly security breaches.

 

Cloud security can make your cloud-based system as safe as a personal computer or device in your pocket—or even safer. With dynamic cloud security in place, you can provide the visibility your IT team needs, along with the control and security to keep your data and systems safe.
