With the multifarious benefits that cloud technologies provide, more and more companies are now migrating their data to the cloud. But with this exodus comes a variety of risks that could undermine these businesses’ credibility, affect their profitability, and expose them to multiple legal consequences.
While cloud environments deal with many of the same kinds of threats that imperil conventional corporate networks, the huge amount of information stored in cloud servers make service providers and enterprises a prominent target among attackers.
According to the Cloud Security Alliance, the most common threats to cloud-based systems include compromised credentials, data theft, attacks by malicious insiders, advanced persistent threats, exploitation of program bugs, denial of service attacks, and account hijacking to orchestrate criminal activities.
In order to counter these threats and avoid their consequences, enterprises should be diligent in their observance of best practices in cloud security. Here are some of them.
Ensure comprehensive visibility
In order for companies to have robust policy control and to enable them to take the necessary steps to secure vital business assets quickly when attacks occur or when vulnerabilities are detected, they need to have comprehensive and continuous visibility into their system. This can be a real challenge, given the fact that modern technology infrastructure environments are very dynamic, automated, and elastic. But by maintaining security tools that are agile, easy to deploy, and can provide complete visibility, businesses can hope to prevent or quickly address such attacks.
Manage exposure and deal with vulnerabilities
Achieving visibility is not enough. Enterprises also need to keep pace with all apparent vulnerabilities in their system so that they can be eliminated before they cause problem. Employing the right monitoring tools and security technologies can help in exposure management.
Furthermore, an action plan for addressing data compromise should be created on top of employing file integrity monitoring, intrusion discovery, and post-breach analysis technologies to allow you to react quickly and minimize the impact of any security breach.
Deploy formidable access control and identity management technologies
Companies need to make sure that proper identity and access management solutions are in place and that they don’t give more access to employees or partners than is required. Otherwise, these will just be gaping holes in their security portfolio. Many high-profile breaches involved the use of valid access-control IDs, with the systems being compromised either by people whose roles didn’t have anything to do with the systems breached or by individuals who no longer have jurisdiction over them.
Encrypt sensitive data
Security teams need to make sure that all critical data are protected and encrypted. Encryption translates vital information into a secret code that cannot be read by outsiders or attackers. Past breaches can be studied in order for companies to have a better idea about the types of data that should be safeguarded. In doing so, enterprises can take the necessary steps to protect such data and to set up measures that would prevent them from being sent outside of the network even if a breach does occur in the future.
