Imagine this scenario: It&#8217;s a very hot day in your city, and you think, &#8220;Why not work from that air-conditioned coffee shop near my house?&#8221; You head over, order a coffee, open your laptop, connect to the &#8220;Café_Free&#8221; network, and start responding to urgent work emails.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> 
To you, it&#8217;s just a few minutes of productivity away from home. But to a Blue Team security analyst monitoring corporate logs, it could be the beginning of a nightmare.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> 
<h2 aria-level="2">What changes when you leave your home or office network?<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> </h2>
To understand why an iced coffee could turn into a corporate nightmare, we need to look at the fundamental difference between where you usually work and where you&#8217;ve decided to sit today.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> 
A private network, whether at home or in the office, is like your house. It has walls, locks on the doors, an alarm system, and a router configured with encryption. When data packets travel from your computer to the router, they pass through a secure tunnel, making it impossible for outsiders to see what&#8217;s being transmitted.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> 
A public network, whether in coffee shops, airports, shopping malls, or hotels, is the digital equivalent of a crowded food court where you shout out your credit card number to pay for your order.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> 
Sounds absurd, doesn&#8217;t it? But the reality is quite close to that example, since public networks are often open (with no password) or use generic, shared passwords. On these networks, there is no isolation between users. Anyone connected to the same network is, theoretically, in the same digital &#8220;room&#8221; as you, creating opportunities for data packets to be intercepted.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> 
<h2 aria-level="2">How does an attacker take advantage of this &#8220;food court&#8221;?<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> </h2>
If public Wi-Fi works like a crowded food court where information is spoken out loud, the cybercriminal is the attentive listener sitting at the next table, discreetly writing down every word. They don&#8217;t need extraordinary skills to intercept your data. They simply need to exploit the open nature of these networks using well-established techniques such as Man-in-the-Middle, Evil Twin, and Session Hijacking.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> 
To understand how this happens, let&#8217;s return to our coffee shop example:<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> 
Man-in-the-Middle literally means an attacker positioned &#8220;in the middle.&#8221; The attacker places themselves virtually between your laptop and the coffee shop&#8217;s router. All information leaving your device passes through the attacker&#8217;s machine before reaching the internet. If that traffic is not properly encrypted, the attacker can read corporate emails, passwords, and confidential documents in real time.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> 
Evil Twin refers to a malicious copy of a legitimate wireless network. The attacker creates a fake access point that replicates the name of the legitimate network (&#8220;Café_Free&#8221;). In many cases, public networks require you to log in through a welcome page before accessing the internet. The criminal takes advantage of that exact moment to clone the login page. Without suspecting anything, you enter your personal or corporate credentials into the fake page, unknowingly handing that information over to the attacker.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> 
Session Hijacking literally means taking control of an active session. Even if you don&#8217;t enter your password while at the coffee shop, the attacker may intercept session cookies already active in your browser. With these cookies, the attacker can &#8220;steal&#8221; your authenticated session and access corporate systems while impersonating you.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> 
<h2 aria-level="2">You&#8217;re connected, but what&#8217;s happening on the other side?<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> </h2>
While you&#8217;re enjoying your coffee, the situation on the other side of the screen is one of high alert. In the <a href="https://it-eam.com/security/soc">SOC</a>, the Blue Team analyst identifies the device&#8217;s exposure when the corporate machine connects to an untrusted network. Without the protection of the company&#8217;s physical firewall, logs begin triggering alerts directly related to the attacks underway, including real-time data interception alerts and suspicious requests to unknown servers.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}"> 
The analyst&#8217;s real nightmare isn&#8217;t just an isolated compromise of your laptop, but the risk of <a href="https://www.ibm.com/us-en/think/topics/lateral-movement">lateral movement</a>. If the cybercriminal manages to install malware or steal your access tokens during those few minutes on the &#8220;Café_Free&#8221; network, they could gain a direct route into the company&#8217;s internal network. The moment you return to the office or reconnect to the corporate network, that malicious file or compromised credential could serve as a bridge for the attacker to access central servers and databases. 
This is precisely where <a href="https://www.crowdstrike.com/en-us/cybersecurity-101/managed-security/">Managed Security Services (MSS)</a> become essential. Since most companies lack the internal resources to maintain a SOC operating 24 hours a day across every remote device, MSS provides the necessary layer of defense through the continuous maintenance and operational support of detection tools and the use of EDR/XDR technologies (designed to protect end-user devices, known as endpoints) to isolate threats in real time. 
Increasingly, the SOC works in coordination with MSS to strengthen the entire incident response process. While the SOC operates core tools such as <a href="https://it-eam.com/en/blog/seguranca/ibm-qradar-siem-and-soar-more-agility-in-threat-detection-and-response">SIEM (Security Information and Event Management) and SOAR (Security Orchestration, Automation, and Response)</a> to identify correlations and automate initial alerts, the MSS team serves as the company&#8217;s right-hand support. MSS analysts conduct in-depth investigations directly within EDR platforms and firewalls, maintain and support SIEM and SOAR tools, and provide the operational expertise needed to execute rapid containment and validation actions. 
This way, an organization&#8217;s security does not depend on where an employee chooses to work, ensuring that mobility does not become a critical vulnerability for the business.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}">

Working from anywhere is one of the greatest benefits of modern work, but the convenience of answering emails over an iced coffee cannot come at the expense of your company&#8217;s data security. It&#8217;s important to emphasize that the line between a few productive minutes away from the office and a serious security incident is thin. All it may take is an unprotected connection and a moment of inattention.<span data-ccp-props="{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:false,&quot;134245529&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}">
