Exploring The Issues Related To The SaaS Model Of Cloud Computing
Posted By : Abhinav Srivastava | 23-Nov-2020
Cloud computing is growing fast due to the digital transformation, expanding penetration of the internet, and extensive big data consumption. One can realize the size of its market with the fact that in 2027, the market valuation will reach US$ 718.07 billion from US$ 252.70 billion in 2019. Cloud computing has three different delivery models viz Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). As a cloud computing solutions provider, we provide effective cloud architecture services to ensure your business chooses the right platform to evolve.
But before that, we will explore the key concerns related to the SaaS model of cloud computing.
Malicious entities on the web prey on enterprises’ data and do the damage. Hence, when you rely on a SaaS model, the security concern becomes more reasonable. It is because, in the traditional on-premise application deployment model, the sensitive enterprise data resided within company premises. Thus, any security issue would directly link to the access control policies of the company and its personnel. However, the SaaS model is outside the enterprise boundaries, with the SaaS vendor.
To ensure the utmost security of the data, the SaaS model must enable additional security steps and tackle data breaches and other malicious activities. Strong encryption techniques are paramount for data security and control of data accessibility. Amazon Web Services provide a strong security layer to prevent any data breach. In AWS, the Elastic Compute Cloud (EC2) administrators having a business need can only access the host after using their cryptographically Strong Secure Shell (SSH) individual keys.

One of the major concerns in the SaaS model is securing the network over which the data exchange between enterprise and SaaS vendor takes place. Since the data flow from the enterprises’ end to the SaaS vendor’s end, it needs to be highly secured to prevent any leakage. Transport Layer Security (TLS) and Secure Socket Layer (SSL) are the two most prominent network encryption techniques.
If we talk about AWS, it protects against network security issues such as Man-in-the-Middle (MITM), packet sniffing, IP spoofing, port scanning, among others. Similarly, Google provides encryption in three states encryption at rest, encryption in transit, and encryption in use. Below is the Application Layer Transport Security (ALTS) protocol by Google, which uses the handshake protocol for authentication and assesses communication parameters before sending any sensitive information.
Multi-tenancy is a major characteristic of cloud computing architecture. It enables multiple users to store their data using applications provided by SaaS. Every user data is isolated and is invisible to other tenants. However, since data from various sources get stored at the same location, we cannot neglect the possibility of an attack.

Malicious entities can find a loophole in the SaaS model to gain unauthorized access to other’s data. They can do so by hacking or by injecting some client code into the SaaS system. In this way, they can trick the system and bypass into anybody’s data with ease. Therefore, the SaaS model must define a clear boundary not only at the physical level but also at the application level. Data segregation is necessary to minimize such intrusions and keep the cloud infrastructure intact.
Migrating from one cloud server to another is not easy at present. Clients can have a tough time switching the cloud servers as and when required. It is one of the major concerns since cloud service providers lock the client to their servers for a certain period. To address this issue, clients must have the clause related to data portability on their contract and an updated copy of data to switch providers in case of any urgency.
