Below are eight common threats that corporate VPNs do not adequately protect against and that SDP does not effectively address.
1. : In this attack, the attacker intrudes into the communication between the user and the application. They either eavesdrop or impersonate one of the parties. SDP and VPN provide protection against these attacks by routing network traffic through an encrypted tunnel. However, SDP continuously protects web traffic and access to the corporate network. Many VPN solutions use split tunneling to route web traffic directly to reduce costs and latency. This leaves the endpoints vulnerable. SDP protects open endpoints.
2. DNS hijacking . This is another danger associated with using public Wi-Fi networks. Attackers can spoof DNS responses, redirecting victims to malicious sites. This is achieved using malicious code or server modification. By gaining control of the DNS, it is possible to redirect users to a web page that appears to be the one requested, but contains additional content (such as advertising), malicious code, or a third-party search engine. An always-on SDP solution based on the network-as-a-service architecture uses a curated, secure DNS service.
3. SSL Removal : This type of man-in-the-middle attack hungary whatsapp data the communication between the endpoint and the server from encrypted to unencrypted in order to be able to read the content. One way to prevent this is to install the HTTPS Everywhere browser extension, which uses the HTTPS protocol wherever possible and does not allow outsiders to switch to HTTP. SDP also prevents this threat by routing all traffic through an encrypted tunnel.
4. DDoS : A distributed denial of service (DDoS) attack is when an application is overloaded with requests and becomes unavailable. Since the attack is distributed, it is difficult to stop. It is designed to prevent legitimate use of the service.
