What is Malware & Anti-Spam Virus | Cloud Antivirus

                              Malware And  Anti-Spam Virus

           

Definition of VIRUS / Malware: A computer virus is a program written with the aim of spreading stealthily and quickly to other computers. It more or less seriously disrupts the functioning of the infected computer. It can spread through any medium of digital data exchange such as the Internet, and in particular through electronic messages or their attachments.

The generic term defining viruses is malware, the term virus is commonly used in an abusive manner to designate all malware. There are different types of malware: viruses, worms, Trojans, or logic bombs, some load in memory, others directly infect the hard drive. Viruses replicate and spread by inserting themselves into other software. Worms spread directly between computers, often through email, file-sharing or the Internet. Trojans, for their part, make it possible to take control of the infected computer or to recover information from its victim.

A virus can either delete or corrupt data. There are also viruses, called ransomware, which encrypt all data on computers and demand a ransom so that you can decrypt and recover your data.

Antivirus is computer software intended to detect and remove viruses and malware from the workstation or stream analyzed. There are over 50 commercial antiviruses out there today and a few open-source antiviruses. The quality of an antivirus largely depends on how quickly it identifies new viruses and updates its antivirus signature base. It is therefore often advantageous to use antiviruses comprising several virus signature databases and/or different antiviruses.

Applications:

Viruses although present in less than 0.5% of emails are potentially very dangerous, a single virus can compromise the entire operation of a company, hence our commitment to do everything possible to block them as well as to build a real fortress against all viruses and malware. This is the reason why ALTOSPAM integrates six complementary antiviruses as well as systems for detecting unknown viruses. All emails and their attached files are systematically scanned successively by these six antiviruses. For more details on the antivirus used, see the page on partners.

Antispam Antivirus Solutions In The Cloud

Spam unnecessarily clogs corporate networks and email servers. In addition, the reception boxes are polluted. In order not to penalize employees and to ward off all computer threats, IT security editors have created the outsourced anti-spam solution. Compared to other filters, it offers a high level of protection at a competitive price.

PRESENTATION OF THE OUTSOURCED ANTI-VIRUS AND ANTI-SPAM SOLUTION

The outsourced anti-spam solution protects users against cyber attacks: viruses, relaying, scams,  denial of service, phishing, etc. It is an email gateway through which company emails pass. They will be processed before being re-routed to its mail server. By using this anti-spam solution, all the security of the email will be outsourced. This service is suitable for small and medium-sized businesses as well as large companies.HE TECHNOLOGIES USED BY THE OUTSOURCED SECURITY SOLUTION

The outsourced anti-spam solution protects users against spam invasion but also against the threats that accompany them. The technologies used by IT security publishers are numerous. Apart from the most classic antivirus and anti-spam, there are also other complementary technologies such as heuristic analysis, blacklists, validation of the sender domain, collaborative spam databases, 'DNS registration, Bayesian filters, whitelist, Domain Keys Identified Mail or DKIM, Sender Policy Framework or SPF teergrubing, greylisting, Turing test, etc.

 

As the user's mail server is no longer visible on the Internet, it will be safe from computer threats. The outsourced anti-spam solution drastically reduces the false positive rate and blocks spam at a very high rate. The availability and lightening of the mail server and the network are guaranteed. The strong point of the outsourced solution is the absence of any architectural modification during its commissioning. Modifying the DNS MX fields will be enough to activate it quickly. It is also compatible with all mail servers. OW ANTI-SPAM SOFTWARE WORKS IN CLOUD antivirus COMPUTING

The operation of the outsourced anti-spam solution is simple. Installed upstream, the security editor's server will first receive all of the company's e-mails. After being processed, they will be sent back to the latter's mail server. In the event that the user's server is unavailable, it is possible for the publisher to keep all of his e-mails for a certain period of time and then the return will be done as soon as it is restored.

 

Strengths and Disadvantages of Anti-virus Anti-spam Solutions in the Cloud

The strong point of the outsourced solution is undoubtedly the existence of a complete administration console where users can follow the processing of all their incoming e-mails step by step. The cost is also a plus for this filter since no significant investment will be required. On the other hand, the filtering is done upstream, it lightens the customer's traffic and secures his business.

The reluctance of companies to use an outsourced anti-spam solution stems from data confidentiality. As opposed to certain structures constrained by the USA Patriot Act to have to disseminate personal information, conversely thanks to the much stricter CNIL concerning personal data, the presence in France of processing centers ensures certain confidentiality of personal information. It is also necessary to ensure the reliability of the service provider in terms of security in order to avoid any risk. The  PCI DSS Certification of the latter guarantees this effort to secure these infrastructures.
