Cybersecurity has become a major issue for all businesses and organizations. Attacks continue to grow and the theft of confidential data can simply lead to the closure of an entity or even influence a presidential election. We propose with this article a list of advices or more exactly of recommendations for your solution of computer security.
Sensitize and train the actors of the information system
A cybersecurity strategy, even thought by the best experts, cannot be successfully applied without an awareness of each actor of the information system. Within a company, all employees are potential targets. As long as each of them does not see himself as a link in the security of his entity, a fault exists and the shield can be pierced. This awareness should ideally take place during training. Without information and knowledge of the threats, the actors of a company are in fact deprived of professional cybercriminals. When the information system is partly or wholly managed by an external provider, it is essential to know its security policy. As every computer hacker is getting modified the results are also perfect now.
Audit the information system
The knowledge of the information system is a prerequisite for the implementation of a security strategy. Sensitive data should be identified and categorized according to their type and importance. Companies may have to manage various files such as contracts, invoices or even documents protected by intellectual property. Once the sensitive data are known, it is necessary to draw up the list of the media on which they are stored. This knowledge makes it possible to set up for each station, server, storage unit, database, specific and adapted security measures. This audit also makes it possible to draw up a diagram of the infrastructure of the information system with among others its interconnections with external or public networks. CCL Servers
Authentication and access control
Auditing an information system not only highlights sensitive data and their location, but also creates specific user roles. These roles control the privileges and access assigned to each user. It is inconceivable for example that in an information system all users have rights “administrators”. A list allowing knowing at all times all the roles but also the registered users must be kept up to date. A company is hired to recruit new employees and see others moving forward. Departure and arrival procedures must therefore be put in place. The ban on anonymous connections is a simple but very effective measure for securing an information system.
Encrypt trade and sensitive data
Sensitive data and exchanges must be encrypted. The audit of an information system not only makes it possible to highlight the sensitive data but also the connections and thus the exchanges between the different components and actors. Many secure protocols rely on the use of SSL / TLS (Transport Layer Security). Its implementation adds to the protocol name the letter S. For hyper-text exchanges HTTP becomes HTTPS, for IMAP email exchanges, POP3 and SMTP become IMAPS, POP3S and SMTPS.
