How to handle destructive malware?

Destructive malware comes through email attachments and messages. Generally. It uses communication tools to spread messages to different clients to create havoc among different consumers. Most of these malwares come in the form of Trojan horses and stages inside different files and folders and spy and send and receive reports to hackers without knowledge of clients. They reach to users in the form of vulnerabilities of websites or in the form of existing computer vulnerabilities. It poses serious risks to organization as hackers can spy on daily operations by receiving data and could exploit these data or could sell these data to competitors so that ultimately, t could pose serious risks to organization as well as their privacies related to securing information of clients.

Most of these cyber attacks, could be seen as events, whereas organization, should seriously inspect the process of planning, detection, preparation and the response times of each processes should be looked into greater detail. The distributed mechanisms from within organizational standards should be seen in greater detail so that ultimately the processes involving entire enterprise resource systems should be completely looked into so that ultimately the security of organizations should have proper and visible security parameters.

The recommended guidance procedure should be looked into the form and factors of detecting network architecture, proper visibility in terms of security baseline and continuous monitoring, and instant response towards incidence response practices. Destructive malwares evolve with due course of time and from time to time it comes in different forms and factors, but still a productive incident response practices within no time should enable proper and distinctive response mechanisms so that organization should always be visible towards such attacks. Destructive malwares be well capable of executing all across, different hosts and end points could entirely paralyze enterprise resource system all across different spheres of organization.

In the move towards potential distribution vectors, organization should seriously patch management systems, asset management systems, remote assistance such as corporate help desk, antivirus, system administrator and network monitoring system, centralized on access back up server both offline and online and file sharing mechanism should be seriously looked into to understand, entire processes of comprehensive security management of organization. From among all these some of these potential distributive vectors such as centralized storage devices which provide direct and conducive access to partitions and ware houses could prove to be serious contender for hackers and that is why extreme security managements in these spheres should be done in first notices. Network devices which could create different ports that could lead to susceptible destructive malwares.

It leads to construction of creating practices and strategic planning practices, where the most common practices securing the entire organization should be looked into greater detail. It is important to make sure, proper network segmentation. Those network segmentation, that are based on network based access control lists which permit server t server and server to host with secure encryption and close all the other forms of unsecured connectivity. Restrictive communication platforms should be there shown that proper management of communication systems should be equally looked into greater detail. Proper implementation of risk assessment and management in the form of layer access control, device level access control enforcement in the form of hardware security should be there within high risk segments such as centralized network servers and storage devices such that these management could be done in proper and systematic manners.

Most of enterprise systems which directly connect with multiple end points and access hosts. Google accounts of individuals are part of enterprise access controls as with a single Google account we could log into different services such as Gmail. Blogger, drive, android devices and the list are endless. One should implement a two factor authentication systems and most of the modern two factor authentication system come in the form of hardware security. Hardware security could be in the form of mobiles or in the form of computers. Similar situation should be implemented in an organization. At enterprise levels all logged by customers and customers should mapped and proper security interface should be implemented.

For each documented enterprise services unique domain management should be used so that mapping and controlling diverse end points should be easily done with. Most clients use service accounts in enterprise resource plannings. Do not grant service accounts to specific customers. As most of the clients are remote users and as organization you do not have so much of an idea of how to deal with such situations as there could have been shouldering surging or unattended computers. Proper auditing and monitoring of security logs for anomalous references could be investigated within administrative privileged service accounts to stop hackers from sending destructive malwares into system.

Log files, system administrator should look into failed logon attempts, file share access mechanisms, and proper vigilantes into interactive logons and the process involving the remote access should be carefully considered and checked into. Next looked deeper into flow of network data and signing of data at different locations. Check out for different ports which could have utilized more data flows unlike to standard operating procedures for network flows. There are some server-ports which are meant for repeated connectivity. In term of command and control purposes and these should be looked into greater security perspectives. One should always ensure and continually, review different network initiatives and communication flows so that in no way unrestricted and unauthorized subset of rules could be injected in the form of destructive malwares.

In order to protect server side vulnerabilities one should utilize role-based access control system to prevent end- user capabilities to be mis-handled. Generally, hackers look for such vulnerabilities to understand these security gaps and could enter into server vulnerabilities. Disable un-necessary and under-utilised features and keep server load to absolute minimal so that you could implement robust security mechanisms. Always remember to check and implement robust security patches before times and reduce zero day vulnerabilities threat so that every time you should be online there should not be an insecurity to system settings.
In the end proper attendances to containment mechanisms such as initiation of enterprise level centralized application, centralized files share system with mapping and double authentication, provide restrictive privilege account so that any insecurity could have into the system properly been rectified.

Create network boundary and resolve DNS server resolution. It is important to implement a network based access control for heuristic prevention so that complete system control mechanisms could be implemented. Apply sandboxing mechanisms so that isolation of specific system control mechanisms could be possible. Always preserve log files and susceptible information so that later these could be subjected to an internal investigation as well as could be a proof for future law enforcement purposes.

*A few days ago. I read a post on us-cert.gov which discussed ‘Handling Destructive Malware’. I’d never hear of this before, but I was intrigued, so I read on.*
