Solution in JavaScript (node.js v5.12) (judge verdict: Accepted)

function Main(input) {
    input = input.split("\n");
    input.shift();
    var arr = new Array(input[0].length+2).fill("#").join("");
    for(var i=0;i<input.length;i++){
        input[i] = "#"+input[i]+"#";
    }
    input.unshift(arr);
    input.push(arr);
    console.log(input.join("\n"))
}Main(require("fs").readFileSync("/dev/stdin","utf8").trim());
