Summary

This blog post will cover how to outsource SEO correctly and avoid the 5 most common mistakes. Google doesn't always work in your favor, and it's important to outsource SEO when you don't have the time or expertise necessary to handle everything that comes with a solid SEO strategy. From keyword research to content evaluation, from page optimization to internal linking, it's easy for companies to end up with a generic web presence that doesn't inspire engagement or drive conversions.

Outsourcing SEO services is a way for brands to identify key strategic goals and then leave the complex process of meeting those goals to industry experts of SEO agencies.

What is CVE?

This short paragraph will briefly introduce the CVE (Common Vulnerabilities and Exposures) numbering system in relation to the three vulnerabilities mentioned above.

In short, the CVE number is a unique reference number used to identify publicly known information about computer security vulnerabilities that can be publicly disclosed. It was created in 1995 by the National Institute of Standards and Technology (NIST). The purpose of this system is to give researchers an easy way to talk about vulnerabilities without having to use long complex names.

Weak SSL/TLS Ciphers and Protocols

A security researcher discovered that some SSL/TLS ciphers and protocols are too weak to secure web traffic. The most severe problem is CVE-2017-3735, a vulnerability in the protocol negotiation for TLS 1.2. This vulnerability affects Chrome on Windows, Mac OS X and Linux. An attacker can exploit this issue by sending an invalid certificate, which will cause Chrome not to display information about the website being visited.
