Cloud security

When moving to the cloud, the inevitable question that needs a proper answer is the question of cloud security. Will your data be safe in the cloud? Will your business become vulnerable to cyber-attacks when shifting to the cloud? Can your cloud service provider safeguard your applications and data from a DDOS attack? How can you ensure that your cloud service is secure? The answer to all these questions is “Cloud Security done right.” Cloud security is a fast-growing service that offers similar features to that of traditional IT security. Cloud security involves protecting critical information from leakage, deletion, and theft. Cloud undoubtedly offers a scalable and flexible network solution with tremendous opportunities. However, the challenges associated with the cloud needs to be appropriately catered to fend off increasingly sophisticated attacks.


How secure is the cloud?

Cloud storage is becoming common each passing day. Data security is hence an increasing concern for organizations who host their data in the cloud. The inevitable question that pops up in the minds of every organization that hosts data in the cloud is the question of how secure the cloud is.

Data that is stored in the cloud is always in an encrypted form. An intruder can access the data only after cracking the encryption mechanism. However, the security of the cloud depends significantly on where the keys to the encryption are held. There are simple ways to extract the keys which are stored either by the cloud service provider or by individual users. Hence, choosing the right cloud solution is of the utmost importance to ensure that data on the cloud is safe.

Data and applications stored in the cloud are secured by the implementation of appropriate technologies and agile practices that are certified by specialized third-party auditors. Cloud providers also take special care on regulatory compliance. A service provider that is audited and certified according to the required standards ensure that the data they place on the cloud is secure.

Cloud service solutions also use appropriate tools and technologies to secure your data in the cloud. Confidentiality is another important aspect that is taken care of. Cloud service solutions also mitigate DDoS attacks and research about the best practices to be adopted to ensure that the data they host is safe from external attacks.


What is cloud security?

Cloud computing allows organisations to store and process their data in third-party servers hosted in the cloud. Organisations use the cloud in different types of service and deployment models. While storing data in the cloud surely has its benefits from the organisational perspective, the responsibility of securing the data is to be shared. Providers of the cloud service must ensure that their infrastructure is secure, while the organisation itself must take measures to properly secure their data using strong passwords, authentication measures, and encryption mechanisms.

Hence, cloud security is achieved both from the organisational as well as the provider level, in order to ensure that the data and services hosted in the cloud are free from external attacks.

How does Denizon achieve cloud security?

The standard addressing method used for Domain Name Systems is “unicast.” This means that a particular DNS server has a dedicated IP Address. Hence, if the server becomes the victim of a DDoS attack, the whole service under this IP becomes affected.

To cater to this problem, Denizon uses Anycast technology. Anycast removes the problems associated with this single point of failure. In the Anycast technology, name servers, distributed as a cloud, advertise the same IP Address. If a DDoS source infests the system, only the Anycast instance nearest to the DoS (Denial of Service) source gets infected. Hence, even when infested by a DDoS attack, the service remains available.

Denizon continuously monitors its network, hardware, applications, and ports for potential vulnerabilities. We deploy the best intrusion detection services that analyze network traffic and generate alerts in response to known patterns of activities.

We also make sure to prevent DDoS attacks on its tracks by monitoring network and hardware continuously. DDoS stands for Denial of Service, and it is a severe threat that brings websites and servers down by bombarding them with requests. DDoS attacks essentially load the target system with a massive number of requests that makes the system lag and reach its downtime. We at Denizon ensure DDoS prevention and mitigation on all levels of the cloud.

Denizon offers DNS failover protection so that the cloud service remains accessible even in the event of an outage. Our monitoring servers make sure that your DNS is instantly updated on all cloud servers as soon as your primary IP fails to respond. Denizon also offers the feature of Disaster recovery in this case so that your data does not get lost when disaster strikes.

Denizon also offers anti-spam, anti-virus and phishing protection to the applications and data that you host on the cloud. We also offer URL filtering options so that threats are stopped at the source and do not enter the cloud network to infest your valuable data.

A secure, dedicated, web-based firewall blocks HTTP traffic, filters specific web applications and acts as a safety gate between servers. Denizon uses a dedicated web-based firewall to block unsecured traffic and mitigate common attacks.

Our compliance policies and procedures put into place ensure that your sensitive data like Credit Card numbers and Social Security numbers are safe from attack.

We carry out regular security audits in order to evaluate your information and to measure how it conforms with our pre-set security criteria. By carrying out a thorough audit, we assess the security of the physical configuration of our infrastructure and the information handling process to determine security compliance and take adequate measures to handle non-conformities.

We also update security patches and carry out compatibility checks regularly to ensure additional security of your applications and data.

A Web Application Firewall (WAF) filters, blocks and monitors HTTP traffic from and to your applications in order to check for Session Poisoning, Buffer Overflow Exploits, SQL injection, and other vulnerabilities. A WAF can prevent attacks from application security flaws.

Denizon deploys WAF protection in its cloud service, ensuring that your applications and data always remain protected from network attacks.

You can remotely access the system hardware using Denizon’s services. With a globalized economy and a geographically spread business, remote access is essential to every organization. We ensure that this remote access does not hamper or trigger infestation of vulnerabilities into your system. We ensure that your remote access mechanism uses strong passwords, firewall systems, lockout policies, and network level authentication in order to secure it from external attacks.

We ensure that we add an extra level of security in your cloud services by offering multi-factor authentication. While multi-factor authentication might seem to be an easy security fix, its positive impacts of cloud security are many. About 81 percent of hacking breaches are password related, and ensuring security on the authentication level means that half of your cloud security needs are met. Another advantage of deploying multi-factor authentication is that the same rules can be applied for all applications and data hosted on the cloud.

Denizon deploys the combination of IDS (Intrusion Detection System) and IPS (Intrusion Prevention System) to secure the cloud. We have real-time IPS and IDS sensors that examine events on your system as well as your network to detect possible intrusion attacks. The IPS and IDS sensors are deployed to copy and monitor the actual traffic.

IDS is a monitoring system that compares network packets to cyber threat databases and flags any matching packets. IPS, on the other hand, is a control system which prevents the flagged packet from entering the system. We regularly update, prepare and make manual adjustments to the IDS and IPS systems to keep it up to date with recent cybersecurity attacks.

Denizon deploys email and web filtering on the cloud. Email filtering is the method of organizing emails according to pre-set specified criteria. We deploy anti-spam techniques that detect spam and phishing emails to save your system from external attacks.

Denizon also offers a web filter service that screens incoming web pages and decides if the content is suitable to be displayed to the user. A set of rules are deployed, and the content/ origin of the web page is checked against the rules. Once, the web page meets all the required standards, only then will the page be allowed to be displayed to the user.

Denizon also offers upload/offload of SSL certificates. SSL offloading is the process of removing SSL based encryption from incoming traffic, to relieve it from decryption of data. Offloading SSL certificates are sometimes referred to as load balancing since it offloads additional tasks from the cloud’s application servers so they can focus on their primary functions.

We also upload custom SSL certificates to secure/encrypt sensitive communication between the cloud components.
