OT Network Security: Fresh Risks, Fresh Requirements

Key infrastructure, like any other properties in the operational technology (OT) sector, faces susceptibility to malicious software and alternative IT security hazards. Just like the incident with the Stuxnet virus, that aimed at the SCADA and PLC systems of a significant nuclear program in the Middle East, no machinery is impervious to breaches or the possibility of being incapacitated by online dangers. Actually, the stakes elevate when pivotal infrastructure is put at risk, reaching the level of national protection. Because of this, contemporary OT sector network security and operational security must precede looming threats that are fresh and continually morphing. 
 
The count of malware attacks and other security occurrences surged in recent times, cyber threats also infiltrated a broader range of industrial fields spanning crucial infrastructure, energy, water, and healthcare sector. A troubling revelation is that the same categories of cyber assaults are applied across multiple sectors. Hence, today’s OT cybersecurity solutions should be adaptable and cater to the security requisites of various sectors.

Why a Versatile OT Security System is Essential

As cyber threats surge, IT security specialists encounter challenges in discovering an optimal security solution for the specific necessities of the OT domain. An appropriate security framework necessitates a great deal of personalization to genuinely safeguard key OT technologies, like SCADA systems. A purpose-built framework considers industrial protocols, application contents, and network commands and data. This idea is particularly valid in tailored market uses such as energy and transportation.

Given that domain-specific OT sectors call for complex and largely tailored setups at diverse control points and gadgets, the security is prone to human faults, resulting in ignored vulnerabilities. To counter this drawback, a centralized network management system facilitates simpler implementation and versatility in assigning authority. Assorted management rights can be allotted to specific regions or functions, diminishing any plausible human faults. The central control platform also supplies enhanced access to data on network flow for assessment.

Why an Intrusion Prevention System Fortifies a Holistic OT Network Defense Mechanism

All OT professionals concur that implementing security patches is vital. Yet, numerous older software and gadgets lack compatibility with fresh patches, which can swiftly become cybersecurity risks in OT applications. Indubitably, updating gadgets in the industrial sector is challenging. These vulnerabilities can be managed with industrial intrusion prevention systems (IPS). Competent in virtual patching to safeguard vulnerable assets, IPS also surveil the network environment, safeguard OT technologies, and deliver security patches in a timely manner without interrupting operations.

IPS can proactively recognize dubious activities and established attack designs in network activity. Once a malevolent activity is spotted, the IPS will invalidate the packet and obstruct traffic from the attacker’s IP address, while still allowing legitimate traffic to proceed. Real-time identification halts external attacks before they can breach exposed systems like SCADA or PLCs. Crafted with the distinct requirements of OT in thought, an IPS security system offers sturdy and dependable features that nullify the guesswork and concerns related to setting up and maintaining a comprehensive defense boundary against cyber perils.
