Network Security in development environments

Development environments have specific needs when it comes to network security, since important information is sent across it. The weight and the value of this information may attract stares and, in these cases, the company must be prepared.

Invasions and attacks on open networks, without any restriction or care, are very common, especially if we consider that most of the development companies use wi-fi (wireless) systems. Anyone with a notebook near the company can connect to the network using programs that find passwords and break security protocols. This is just one of the possible chaos scenarios that can be mapped on the environment, but a multitude of other cases can be found.

But if on the one hand there are malicious users trying to carry out attacks, on the other we have professionals who specialize in stopping such actions with tools that are essential in the preservation of data traveling on the network. These professionals within the organization are responsible for setting up and defining action plans and contingency in case of invasions and attacks. By default, they define policies, rules of use, equipment configuration and programs that will prevent malicious actions on networks. Among the many actions taken by the network security responsibles, we include:

Risk Mapping on the organization’s network;
Creation, analysis, implementation and validation of network security policies;
Firewall configuration;
Use of detection system for intruders;
Insert of encryptions and PKIs;
VPN usage possibility for external connections;
Validation of the user authentication process;
Environments settings focusing on permissions and access profiles;
Creation, analysis and implementation of security models.

Map and monitor the actions on the network takes time and effort, so it is important not to underestimate routine actions of those who need to ensure the security process. Awareness of the organizational environment at all levels is essential for all created policies to be effectively applied. In case of internal security protocol breaks, sanctions should be adopted in order to avoid losses to the business. In cases where the threat is given externally, it is necessary that, when identifying the offender, appropriate legal measures are taken. Thus, having a well-aligned security process is fundamental in order to ground penalties and decisions in any of the situations.
